What is pH?
The ratio of acid and base in any solution is called acid-base balance (ABA), although physiologists believe that it is more correct to call this ratio the acid-base state. KShchR is characterized by a special indicator pH (power Hydrogen - "strength of hydrogen"), which shows the number of hydrogen atoms in a given solution.

Acid-base balance is our indicator of health. The more acidic we are, the sooner we age and the more we get sick. You have probably heard about antioxidants, that you need to eat more fresh fruits and vegetables in order to protect your cells from stress, aging and death, and the body from oxidation. And that water and fresh vegetable food helps us to keep youth and beauty.

Let's take a closer look at the topic and find out how seriously environmental factors affect the quality and duration of our lives. Further - figures, facts and practical advice.

The main cause of disease today is an excess of acid-forming foods in our diet, leading to the accumulation of acidic deposits in cells and tissues. Cancer cells and other diseases can only develop in an acidic environment. Even the common cold virus is difficult to survive in an alkaline environment.

Has a substance of an acidic or alkaline nature, is determined by the value of PH (means potential hydrogen). The standard pH scale is graduated from 1 to 14 units, 7 is taken as a neutral value. A substance with a pH less than 7 is acidic, and a substance with a pH greater than 7 is alkaline.

At a pH of 7.0, they speak of a neutral environment, the lower the pH level, the more acidic the environment is from (6.9 to 0). An alkaline environment has a high pH level from (7.1 to 14). The pH value depends on the ratio between positively charged ions (forming an acidic environment) and negatively charged ions (forming an alkaline environment). The body is constantly trying to balance this ratio, maintaining a strictly defined level of pH. When the balance is disturbed, many serious diseases can occur. Check your acid-base balance with test strips.

It is very important to pay attention in time to changes in the pH level of the internal environment of the body and, if necessary, take urgent measures. With the help of pH test strips, you can easily, quickly and accurately determine the pH level without leaving your home. If the pH level of urine fluctuates between 6.0-6.4 in the morning and 6.4-7.0 in the evening, then your body is functioning normally. If the pH level in saliva remains between 6.4-6.8 throughout the day, this also indicates the health of your body. The most optimal pH level of saliva and urine is slightly acidic, in the range of 6.4-6.5. The best time to measure the pH level is one hour before a meal or two hours after a meal. Check the pH level 2 times a week 2-3 times a day.

When applied to nutrition, natural foods such as fruits and vegetables are alkaline-forming only to a moderate degree. Animal protein foods are acid-forming to a very high degree.

If an ideal balance of alkali-forming and acid-forming products is maintained in the diet, then the resulting alkalis and acids neutralize each other and leave a PH - neutral precipitate.

In a healthy body there are reserves of alkaline elements - a kind of bank account. And if we eat a piece of meat, alkaline substances are automatically removed from the body's reserves to neutralize it. But if we eat meat constantly, then these reserves are quickly depleted, and the body loses the ability to neutralize the resulting acids. To continue the analogy with a bank account, it's like withdrawing money from the account endlessly without replenishing it.

To ensure regular replenishment and maintenance of alkaline reserves, the 80/20 rule must be followed. According to this rule, 80% of the foods we consume should be alkaline-forming, and 20% acid-forming.

When you first urinate in the morning, check the acidity of the urine using a pH indicator - a piece of specially treated paper. If the pH level is 5.5 or less, then the acidity level is high and your body needs alkalizing. Morning urine should have a pH of 6. Most people with joint pain have a pH of 4.5, which means that a lot of uric acid precipitates overnight. This can cause severe pain in the morning. During the day, the pH of the urine tends to rise as the acid deposits are neutralized and the patient feels better.

To alkalize urine, mix two parts baking soda and one part sodium potassium mixture in a glass jar. Dissolve a teaspoon of this topless mixture in a glass of water (not cold) and drink before bed (not earlier than 2 hours after dinner). Drink everything at once if possible. The next morning, the urine pH should rise to 6. If this does not happen, increase the dosage to a spoonful with a top.

Check the pH from time to time, as to maintain the pH = 6, you will have to gradually reduce the dose. If you alkalize your urine before bed, the pH of your urine will not drop too low overnight. This will reduce the deposition of salts in the joints and will not allow the dissolved kidney crystals to crystallize again, forming new stones.

Increased acidity in the body.

An imbalance in the pH of the body in most people manifests itself in the form of increased acidity (the condition Acidosis). In this state, the body does not absorb minerals such as calcium, sodium, potassium and magnesium, which, due to excess acidity, are excreted from the body. Vital organs suffer from a lack of minerals. Acidosis not detected in time can harm the body imperceptibly, but constantly for several months and even years. Alcohol abuse often leads to acidosis. Acidosis can occur as a complication of diabetes.

Acidosis can cause the following problems:
- Diseases of the cardiovascular system
- Diseases of the kidneys and bladder, the formation of stones.
- Decreased immunity
- Increased harmful effects of free radicals, which can contribute to oncogenesis.
- Fragility of bones up to a fracture of the femoral neck, as well as other disorders of the musculoskeletal system, such as the formation of osteophytes (spurs).
- The appearance of joint pain and pain in the muscles associated with the accumulation of lactic acid.

Increased alkali content in the body.

With an increased content of alkali in the body, and this condition is called Alkalosis, the absorption of minerals is disturbed. Food is absorbed much more slowly, which allows toxins to penetrate from the digestive tract into the blood. The increased content of alkali in the body is dangerous and difficult to correct. As a rule, it is the result of the use of medicines containing alkalis.

As I said, the pH level of blood and other fluids in our body should fluctuate. from 7.35 to 7.45. The average blood pH of a healthy person is 7.42. What do these numbers depend on? First of all, from nutrition and external factors.

Inattentive attitude to food, choice of unhealthy food, harmful drinks and other factors - smoking, alcohol, stress. All these aspects contribute to lowering the pH.

We eat and drink every day, we inhale tobacco smoke next to a smoking person or smoke ourselves, we are nervous because of a mortgage, emergency work at work, antics of our children or relationships in the family. All this does not add to us either youth or health. It is clear that it will not be possible to influence all factors at once, but today we can start small. Start thinking and consciously choose drinks and food. Just this one small step will allow you to improve your health by an order of magnitude.

All foods are divided into acidic and alkaline.
Familiar to us: potatoes (old), any starchy vegetables, unripe fruits, pasteurized milk, yoghurts with added sugar, all meat and fish, clarified refined vegetable oil, sugar, pastries, pasta, old nuts, vinegars (except apple) - all this acidic foods that lower the pH level in the body.

Drinks are also divided into oxidizing and alkalizing. Coffee, black tea, cocoa, lemonades and juices from packs oxidize the blood, and high-quality water, weak hibiscus tea, herbal teas, on the contrary, alkalize the body.

The category of neutral products includes:
buckwheat, oats, rye, brown rice, wholemeal flour products, unrefined vegetable oils (obtained by pressing or cold pressing).

Of course, it is impossible to completely eliminate acidic foods from the diet, but you still need to maintain a balance. This will allow you to maintain a high level of immunity and avoid many diseases.

Basic rules for choosing food and drinks.

The best drink- This is water. We have already found this out in the past.
The best food- fresh vegetables, fruits, herbs, sprouted grains and legumes. Thermally untreated! If you include a kilogram of fresh vegetables and fruits in your diet every day, eat a handful of sprouts and drink the minimum norm of high-quality water (30 ml per 1 kg of weight), then your health will be much better than those people who have coffee with sandwiches for breakfast, they dine with a chop with potatoes and soup, and dine with a casserole.

Our blood, lymph, pericellular fluid are responsible for the activity of the body, the quality and duration of life. We must provide the body with building materials, nutrients, oxygen, and not satisfy our taste preferences. Then we can enjoy life, and not look for pills and a doctor who will think about how to sort out our troubles.

By the way, a curious fact - your the love of sugar also adversely affects the protective functions of the body.

6 tablespoons of sugar per day, reduce immunity by 25% for 24 hours.
. 12 tablespoons of sugar for 60% per day.
. And 18 tablespoons of sugar and does 85% per day.

At the same time, it is worth considering the hidden sugars that are in food and sweets, and not just put in tea or coffee. Therefore, if you love yourself and want to be healthy, give up sugar. I did it in one day, two years ago. I just decided not to use it anymore. By the way, for 6 months without changing anything in my diet, I then lost 5 kg. Of course, I can afford to eat a cake at a party and a chocolate bar, but this is not my daily meal. I drink tea without sugar and without honey. And I feel great. All our eating habits are nothing more than habits. And they can and should be changed if you want to live healthy and bright.

Diet to restore pH levels

The alkaline diet is applicable to normalize the pH level in the body. This diet is good not only for weight loss, but also has a positive effect on human health. So if you are overweight, then the alkaline diet is for you! You will lose extra pounds and at the same time equalize the acid-base balance.

Alkaline and acid foods
All foods that we eat can be divided into acid-forming, alkali-forming and neutral. This division is based on their effect on our body after they are digested. Human blood is alkaline in nature. And to maintain its optimal pH level, a person should consume 80% alkaline foods and 20% acidic. But in an era of artificial substitutes, preservatives and emulsifiers, the average person's diet is far from this ideal balance. But it is not at all difficult to correct it by knowing which products need to be excluded, and the use of which should be increased.

The principle of the acid-base diet
So, we need to achieve a ratio of alkaline to acidic foods equal to 4 to 1. But the transition to this diet should be smooth. It is necessary to gradually replace fried, boiled food and animal products with fresh vegetables and fruits, which must be eaten without heat treatment. To make it easier for you to navigate and compose your diet, below we provide a list of products by acidity.

acidic foods
1. Any semi-finished products or finished products.
2. Any sweets containing white sugar.
3. Fried and cooked foods (even vegetables)
4. All fats and oils.
5. Bakery products such as: buns, white bread and any products made from white flour. Cereals and legumes: wheat, corn, rice and beans. We also write polished rice here.
6. Meat, eggs, fish, poultry and any animal products, including oil and any fat. As well as dairy products, cheese and cottage cheese.
7. Products containing toxins: alcohol, tobacco, soft drinks (eg soda), coffee, tea.
8. Any dried nuts and seeds.

alkaline foods
1. All fresh or dried fruits. The exceptions are cranberries, blueberries, currants, prunes, plums.
2. All raw vegetables. The exceptions are peas, legumes, rhubarb, Brussels sprouts and large-fruited pumpkin, as well as vegetables of the nightshade family (tomatoes, potatoes, peppers, eggplants)
3. Sprouted grains and legumes.

Partially alkaline foods
1. Fresh raw milk and cottage cheese
2. Soaked nuts and seeds
3. Fresh nuts: almonds, coconut, brazil nuts
4. Fresh green beans, peas, grains and millet

Note: even seemingly acidic fruits like lemon, pineapple or orange are alkaline.

Ways to Increase Alkalinity
. By adding lecithin to food or drinks.
. Drink freshly squeezed lemon juice dissolved in a glass of hot or cold water.
. Drink freshly squeezed fruit juices from grapes, pear, apricot, papaya, mango, pineapple, grapefruit and orange.
. Only fresh or stewed fruits.
. Drink fresh vegetable juices from carrots, celery, beets, parsley, spinach, onions.
. 5 days a week before going to bed, drink a glass of clean water with 3-5 drops of glycothymoline
. Drink non-carbonated mineral waters (Borjomi, Essentuki-4, Smirnovskaya)
. Bowel movements 2-1 times a day.
. Try to move during the day or exercise.

Biochemically, increased acidity of the body is equivalent to the sudden onset of old age. Hence the general decline, fatigue and depression.

The alkaline diet is really very healthy and will definitely appeal to people who care about their health. It may be difficult at first to completely change your diet, but it's worth it!

What to eat for health? The main work on the synthesis of nutrients occurs in the intestine. Therefore, we need to take care of our beneficial microflora.
E. coli eats only fresh plant foods, seeds, nuts, dairy products. That's when it can synthesize the amino acids, vitamins and other building materials that we need so much.

By the way, doctors and scientists have already established that all cancer patients have a lower blood pH than healthy people. The average blood pH of a cancer patient is below 7.35…

A decrease of only 5 tenths can lead to irreversible processes. Take care of yourself, love yourself. You are alone! And you have one body, for life.

Take your food choices more seriously, not everything that smells good should be put in your mouth. Too expensive price for a minute pleasure.

Remember:

A neutralization reaction is a reaction between an acid and a base that produces salt and water;

By pure water, chemists understand chemically pure water that does not contain any impurities and dissolved salts, that is, distilled water.

Acidity of the environment

For various chemical, industrial and biological processes, a very important characteristic is the acidity of solutions, which characterizes the content of acids or alkalis in solutions. Since acids and alkalis are electrolytes, the content of H + or OH - ions is used to characterize the acidity of the medium.

In pure water and in any solution, along with particles of dissolved substances, there are also H + and OH - ions. This is due to the dissociation of the water itself. And although we consider water to be a non-electrolyte, nevertheless it can dissociate: H 2 O ^ H + + OH -. But this process occurs to a very small extent: in 1 liter of water, only 1 decomposes into ions. 10 -7 mol molecules.

In acid solutions, as a result of their dissociation, additional H+ ions appear. In such solutions, there are much more H + ions than OH - ions formed during a slight dissociation of water, therefore these solutions are called acidic (Fig. 11.1, left). It is customary to say that in such solutions an acidic environment. The more H+ ions are contained in the solution, the greater the acidity of the medium.

In alkali solutions, as a result of dissociation, on the contrary, OH - ions predominate, and H + cations are almost absent due to the insignificant dissociation of water. The environment of such solutions is alkaline (Fig. 11.1, right). The higher the concentration of OH - ions, the more alkaline the solution medium is.

In a solution of table salt, the number of H + and OH ions is the same and equal to 1. 10 -7 mol in 1 liter of solution. Such an environment is called neutral (Fig. 11.1, center). In fact, this means that the solution contains neither acid nor alkali. A neutral environment is characteristic of solutions of some salts (formed by alkali and strong acid) and many organic substances. Pure water also has a neutral environment.

Hydrogen indicator

If we compare the taste of kefir and lemon juice, then we can safely say that lemon juice is much more acidic, that is, the acidity of these solutions is different. You already know that pure water also contains H+ ions, but the water does not taste sour. This is due to the too low concentration of H+ ions. Often it is not enough to say that the environment is acidic or alkaline, but it is necessary to characterize it quantitatively.

The acidity of the environment is quantitatively characterized by the hydrogen indicator pH (pronounced "p-ash"), associated with the concentration

hydrogen ions. The pH value corresponds to a certain content of hydrogen cations in 1 liter of solution. In pure water and in neutral solutions, 1 liter contains 1. 10 7 mol of H + ions, and the pH value is 7. In acid solutions, the concentration of H + cations is greater than in pure water, and less in alkaline solutions. In accordance with this, the pH value also changes: in an acidic environment, it ranges from 0 to 7, and in alkaline environments, from 7 to 14. For the first time, the Danish chemist Peder Sørensen suggested using the pH value.

You may have noticed that the pH value is related to the concentration of H+ ions. Determining pH is directly related to calculating the logarithm of a number, which you will study in math lessons in grade 11. But the relationship between the content of ions in a solution and the pH value can be traced according to the following scheme:

The pH value of aqueous solutions of most substances and natural solutions is in the range from 1 to 13 (Fig. 11.2).

Rice. 11.2. pH value of various natural and artificial solutions

Søren Peder Lauritz Sørensen

Danish physical chemist and biochemist, President of the Royal Danish Society. Graduated from the University of Copenhagen. At 31, he became a professor at the Danish Polytechnic Institute. He headed the prestigious physical and chemical laboratory at the Carlsberg brewery in Copenhagen, where he made his main scientific discoveries. His main scientific activity is devoted to the theory of solutions: he introduced the concept of hydrogen index (pH), studied the dependence of enzyme activity on the acidity of solutions. For scientific achievements, Sørensen is included in the list of "100 outstanding chemists of the 20th century", but in the history of science he remained primarily as a scientist who introduced the concepts of "pH" and "pH-metry".

Determination of the acidity of the medium

To determine the acidity of a solution in laboratories, a universal indicator is most often used (Fig. 11.3). By its color, one can determine not only the presence of acid or alkali, but also the pH value of the solution with an accuracy of 0.5. For a more accurate measurement of pH, there are special devices - pH meters (Fig. 11.4). They allow you to determine the pH of the solution with an accuracy of 0.001-0.01.

Using indicators or pH meters, you can monitor the progress of chemical reactions. For example, if hydrochloric acid is added to a solution of sodium hydroxide, then a neutralization reaction will occur:

Rice. 11.3. A universal indicator determines the approximate pH value

Rice. 11.4. To measure the pH of solutions, special devices are used - pH meters: a - laboratory (stationary); b - portable

In this case, the solutions of the reactants and reaction products are colorless. If, however, the electrode of a pH meter is placed in the initial alkali solution, then the complete neutralization of the alkali with acid can be judged by the pH value of the resulting solution.

The use of the pH indicator

Determining the acidity of solutions is of great practical importance in many areas of science, industry and other areas of human life.

Environmentalists regularly measure the pH of rainwater, rivers and lakes. A sharp increase in the acidity of natural waters may be the result of atmospheric pollution or the ingress of waste from industrial enterprises into water bodies (Fig. 11.5). Such changes entail the death of plants, fish and other inhabitants of water bodies.

The hydrogen index is very important for studying and observing the processes occurring in living organisms, since numerous chemical reactions take place in cells. In clinical diagnostics, the pH of blood plasma, urine, gastric juice, etc. is determined (Fig. 11.6). Normal blood pH is between 7.35 and 7.45. Even a small change in the pH of human blood causes serious illness, and at pH = 7.1 and below, irreversible changes begin that can lead to death.

For most plants, soil acidity is important, so agronomists analyze soils in advance, determining their pH (Fig. 11.7). If the acidity is too high for a particular crop, the soil is limed - chalk or lime is added.

In the food industry, with the help of acid-base indicators, food quality control is carried out (Fig. 11.8). For example, the normal pH for milk is 6.8. A deviation from this value indicates either the presence of impurities or its souring.

Rice. 11.5. The influence of the pH level of water in reservoirs on the vital activity of plants in them

The pH value of the cosmetics that we use in everyday life is important. The average pH for human skin is 5.5. If the skin comes into contact with agents whose acidity differs significantly from this value, then this leads to premature aging of the skin, its damage or inflammation. It was noticed that laundresses who used regular laundry soap (pH = 8-10) or washing soda (Na 2 CO 3 , pH = 12-13) for washing for a long time, the skin of the hands became very dry and cracked. Therefore, it is very important to use various cosmetic products (gels, creams, shampoos, etc.) with a pH that is close to the natural pH of the skin.

This is textbook material.

Surely many have heard more than once about such a concept as pH (neutral, acidic or alkaline). This is an indicator of hydrogen, and it can be found both on a tube of cream and at a dermatologist's appointment. Information about the pH of the skin is very important. What is this indicator? Let's try to figure it out.

A little about the structure of the skin

As you know, the stratum corneum, located in the epidermis of the skin, performs the function of protection. It contains a water-lipid matrix containing fatty compounds and the acid mantle of Marchionini. Many people believe that its pH is neutral - about 7, but this is a misconception. Covers with this will be dry and tight. The skin contains milk and lemon in its composition, which means that its balance should not go beyond the sour. If any disturbances or changes occur in the dermis, then the pH of the epidermis begins to change dramatically. This can be both a consequence of a serious illness, and the result of improper skin care.

pH scale

First of all, you need to remember that the concept of “pH neutral” applies specifically to the environment in question. Regarding the skin, its value is 5.2-5.7, tears - 7.4, and in chemical solutions, the neutral pH is 7 units (for example, water).

From chemistry lessons, we know that the acid-base balance scale ranges from 0 to 14. Neutral pH is about half, anything lower is acidic, anything higher is alkaline. As for the concepts in cosmetology, “pH neutral” means that such an acid-base indicator is the most optimal for any skin.

In addition, oily skin is also determined by this very indicator. Dry skin has a pH of 5.7 to 7, normal skin has a pH of 5.2 to 5.7, and oily skin has a pH of 4 to 5.2.

Skin problems: vicious circle

We have already figured out what pH is, and now let's talk about the problems associated with this indicator. Oily skin is a problem for many people. Especially in adolescence. Almost every child inevitably develops pimples and acne. Of course, this is a consequence of a temporary failure in the hormonal background. However, it is at this time that proper skin care is very important.

What do parents advise in this case? Wash more often? The teenager does so, but the acne only gets worse. What is the reason? Soap is alkaline and its pH ranges from 6 to 11. Its frequent use leads to the fact that it washes away the top layer of the face with an acidic environment. The protective function of the stratum corneum works in such a way that the less beneficial acidic bacteria present in the normal flora of the face on the skin, the more it produces subcutaneous fat. Here is a vicious circle: the more we wash, the more oily skin becomes. A natural question arises: "What to do?"

How to keep pH normal?

In order to maintain its natural acid-base balance when washing the face, it is necessary to pay special attention to the cosmetics used in this process. The first step is to find out which neutral pH soap can be used for frequent washing. If this is really a forced measure, then the hydrogen base must be acidic (up to 5.5 units). These include special foams, gels, scrubs for washing for oily skin (pH = 4).

If there are no problems as such, then for care you can use products with a slightly acidic reaction, 5.5 units, for dry skin - closer to neutral - 6.5. In any case, it must be remembered that in order to choose the right skin care product, it is necessary to roughly equalize the acid-base balance. The same goes for other skin care products. A gel with a neutral pH is usually suitable for dry skin, and for problematic ones, it is worth choosing products with a slightly acidic environment.

Shampoo and pH

Like any substance, shampoo also has its own pH, and it is different for each brand. Here, according to the laws of chemistry, exactly the same rule applies: a low indicator of up to 7 units is acidic, higher is alkaline. Shampoos with a neutral pH level - exactly 7 units. Regarding the scalp, almost everything remains unchanged. Normally, she has a more slightly acidic environment - 4.5-5.5. This means that the choice of shampoo should entirely depend on how oily the scalp is.

For dry types, it is recommended to use more alkaline shampoos, and for oily ones, slightly acidic ones. If the scalp is picky, such as children's, then you need to choose shampoos with a neutral pH (7 units). Unfortunately, only a small number of manufacturers indicate which acid-base indicator is present in their cosmetic product. They are limited only to inscriptions (for dry, for oily, for normal skin). This is not entirely correct, because, according to research, it turns out that, as a rule, shampoos for normal skin are alkaline, and should be slightly acidic.

Is it possible to determine the pH level of the skin and products?

Many people would like to know the water-acid balance in a particular substance. At home, doing the test is not difficult. This requires a solution and an acid-base indicator, usually litmus strips. They are dipped into the solution and placed on white paper. Color appears almost instantly on the indicator. According to the proposed color scale, you can determine whether it is alkaline. For example, if litmus is dipped in alkali, it will give a blue color, in an acidic environment - red.

Another way to find out what the pH is is with a pH meter. This is a very popular device with high accuracy. It is used in industries where environmental control is necessary (fuel production, chemical and paint industries, etc.). Such a device can also be found at a dermatologist's appointment. In this article, we studied what pH is and found out how to choose the right skin care products according to their acid-base balance.

The hydrogen index - pH - is a measure of the activity (in the case of dilute solutions it reflects the concentration) of hydrogen ions in a solution, quantitatively expressing its acidity, calculated as a negative (taken with the opposite sign) decimal logarithm of the activity of hydrogen ions, expressed in moles per liter.

pH = – lg

This concept was introduced in 1909 by the Danish chemist Sorensen. The indicator is called pH, after the first letters of the Latin words potentia hydrogeni - the strength of hydrogen, or pondus hydrogenii - the weight of hydrogen.

The reciprocal pH value has become somewhat less widespread - an indicator of the basicity of the solution, pOH, equal to the negative decimal logarithm of the concentration in the solution of OH ions:

pOH = – lg

In pure water at 25 ° C, the concentrations of hydrogen ions () and hydroxide ions () are the same and amount to 10 -7 mol / l, this directly follows from the water autoprotolysis constant K w, which is otherwise called the ion product of water:

K w \u003d \u003d 10 -14 [mol 2 / l 2] (at 25 ° C)

pH + pOH = 14

When the concentrations of both types of ions in a solution are the same, the solution is said to be neutral. When an acid is added to water, the concentration of hydrogen ions increases, and the concentration of hydroxide ions decreases accordingly, when a base is added, on the contrary, the content of hydroxide ions increases, and the concentration of hydrogen ions decreases. When > they say that the solution is acidic, and when > - alkaline.

pH determination

Several methods are widely used to determine the pH value of solutions.

1) The pH value can be approximated with indicators, accurately measured with a pH meter, or determined analytically by performing an acid-base titration.

For a rough estimate of the concentration of hydrogen ions, acid-base indicators are widely used - organic dye substances, the color of which depends on the pH of the medium. The most famous indicators include litmus, phenolphthalein, methyl orange (methyl orange) and others. Indicators can exist in two differently colored forms, either acidic or basic. The color change of each indicator occurs in its acidity range, usually 1-2 units (see Table 1, lesson 2).

To extend the working range of pH measurement, the so-called universal indicator is used, which is a mixture of several indicators. The universal indicator consistently changes color from red through yellow, green, blue to purple when moving from an acidic to an alkaline region. Determination of pH by the indicator method is difficult for cloudy or colored solutions.

2) The analytical volumetric method - acid-base titration - also gives accurate results for determining the total acidity of solutions. A solution of known concentration (titrant) is added dropwise to the test solution. When they are mixed, a chemical reaction takes place. The equivalence point - the moment when the titrant is exactly enough to completely complete the reaction - is fixed using an indicator. Further, knowing the concentration and volume of the added titrant solution, the total acidity of the solution is calculated.

The acidity of the environment is important for many chemical processes, and the possibility of the occurrence or the result of a particular reaction often depends on the pH of the environment. To maintain a certain pH value in the reaction system during laboratory research or in production, buffer solutions are used that allow you to maintain a practically constant pH value when diluted or when small amounts of acid or alkali are added to the solution.

The pH value is widely used to characterize the acid-base properties of various biological media (Table 2).

The acidity of the reaction medium is of particular importance for biochemical reactions occurring in living systems. The concentration of hydrogen ions in a solution often affects the physicochemical properties and biological activity of proteins and nucleic acids; therefore, maintaining acid-base homeostasis is a task of exceptional importance for the normal functioning of the body. Dynamic maintenance of the optimal pH of biological fluids is achieved through the action of buffer systems.

3) The use of a special device - a pH meter - allows you to measure pH in a wider range and more accurately (up to 0.01 pH units) than using indicators, is convenient and highly accurate, allows you to measure the pH of opaque and colored solutions and therefore widely used.

Using a pH meter, the concentration of hydrogen ions (pH) is measured in solutions, drinking water, food products and raw materials, environmental objects and production systems for continuous monitoring of technological processes, including in aggressive environments.

A pH meter is indispensable for hardware monitoring of the pH of uranium and plutonium separation solutions, when the requirements for the correctness of equipment readings without its calibration are extremely high.

The device can be used in stationary and mobile laboratories, including field laboratories, as well as clinical diagnostic, forensic, research, industrial, including meat and dairy and baking industries.

Recently, pH meters have also been widely used in aquarium farms, household water quality control, agriculture (especially in hydroponics), and also for monitoring health diagnostics.

Table 2. pH values ​​for some biological systems and other solutions

Another important parameter that determines the properties of living water is pH.

Catholyte or living water has an alkaline pH ranging from 7 to 12.

What is the significance of this notorious pH for our body? What does this parameter, which is so often mentioned recently in advertising of soaps, creams and toothpaste, mean?

Every day, when eating, breathing and moving in the process of metabolism, a huge amount of acids and alkalis is formed in the body. For a living organism to exist, three conditions must be met.

1. A certain amount of acids and alkalis must be removed.

2. A certain amount of acids and alkalis should be used for the needs of the body.

3. A certain ratio must be maintained between acids and alkalis - the so-called acid-base balance.

To characterize the acid-base balance, pH is used - an indicator of the acidity or alkalinity of a solution, which is determined by the concentration of H + and OH ions. .

The pH value can only vary from 0 to 14, and the product of H + and OH - ions will always be 14. Therefore, it is not necessary to know the concentration of both H + ions and OH - ions. It is enough to know one of the indicators. It so happened that the concentration of hydrogen ions H + was chosen as this indicator. It characterizes the acidity of the solution, since each acid dissociates into hydrogen ions and an acid residue. And since the concentrations of H + ions in solutions can differ hundreds of trillions of times - from 10 -14 mol / l (strong alkali solutions) to 10 mol / l (concentrated hydrochloric acid), we agreed to indicate only the exponent 10, taken with the opposite sign . Hence the notorious “pi-logarithm” arose.

An acidic solution has a pH<7.

An alkaline solution has a pH > 7.

The pH of neutral solutions is 7.

Since human organs and tissues consist of 70–80% of an aqueous solution, each of them has strictly defined acidity limits and can only work within these limits. Changes in the pH value lead to illness or even death.

The boundaries of the pH parameter for blood are especially strictly marked - 7.37-7.45 for arterial and 7.32-7.42 for venous. Venous blood is more acidic because it is saturated with carbon dioxide. Man can only live at these pH values. Deviations in blood pH below 7.3 and above 7.5 are accompanied by severe consequences for the body. At a blood pH of 6.95, loss of consciousness and death occur. If the concentration of H + ions decreases and the pH becomes 7.7, severe convulsions (tetany) occur, which can also lead to death.

The digestive enzymes of the pancreas function normally at a pH of 8.3.

The normal pH of liver and gallbladder secretion is 7.1.

Saliva pH is 6.0–7.9. When the body is oxidized, primarily the pH of saliva and urine changes.

Connective tissues have a pH of 7.08 to 7.29.

muscle pH - 6.9. For muscle tissue, the pH value can vary over a wider range than for blood. Muscle tissue needs constant acid removal. So, when the pH drops below 6.2, the heart muscle stops working and the heart stops.

The kidneys are one of the main organs that remove or neutralize excess acids. The acidity of urine, along with the acidity of saliva, is the main indicator of acid-base balance. Urine is characterized by pH values ​​from 4.5 to 7.7. It is very important that the pH of the night urine is different from the pH of the morning and day. The reaction of urine determines the possibility of stone formation. Uric acid stones are more often formed at a pH below 5.5, oxalate - at pH = 5.5-6.0, phosphate - at pH = 7.0-7.8.

Gastric juice has the most acidic pH in the body, ranging from 1.6 to 1.8. The activity of pepsin, an enzyme that catalyzes the hydrolysis of proteins and promotes the digestion of meat, sausage, milk, cheese and other protein foods in the stomach, depends on the acidity of gastric juice. Therefore, for normal digestion, it is necessary that the gastric juice has exactly these pH values. Changes in pH - there are diseases. So, with gastric ulcer, the pH drops to 1.48.

Acidosis- one of the forms of violations of the acid-base balance of the body, characterized by an absolute or relative excess of acids, that is, substances that donate hydrogen ions (protons).

acidosis may be compensated and uncompensated depending on the pH of the blood. With compensated acidosis, blood pH shifts to the lower limit of the physiological norm (7.35). With a more pronounced shift to the acid side (pH less than 7.35), acidosis is considered uncompensated.

As a result of metabolism in the body, a large amount of acids is formed in two forms: flying(coal) and non-volatile(fixed).

Carbonic acids formed during cell metabolism are called volatile. These acids are then released by the cells as H+ ions, attached to hemoglobin, and transported to the lungs. In the lungs, hemoglobin gives off H + ions, which, by binding to bicarbonate, form carbon dioxide, which is removed during breathing. At rest, the body releases 230 ml of CO 2 per minute, or about 15,000 mmol per day.

As a result of the metabolism of proteins and other acid-forming products, non-volatile(non-carbonic or fixed) acids such as sulfuric and phosphoric. Daily, with a normal diet, only due to the formation of non-volatile acids, about 1 mmol / l of hydrogen ions is produced per kilogram of body weight. If these acids were not constantly neutralized and removed, then in a day the pH would drop to 2.7. . An excess of non-volatile acids can occur when they are taken too much from food or as a result of various diseases characterized by the accumulation of acidic products in tissues, their insufficient binding or destruction.

So, with diabetes, fasting, high fever, alcohol intoxication, extensive inflammatory processes, injuries, burns, ketoacidosis(increased production of ketone bodies). A large concentration of these decay products causes poisoning of the central nervous system (manifested by headaches or weakness) in diabetes - up to the development of a diabetic coma.

With cirrhosis of the liver, decompensation of cardiac activity, insufficient oxygen supply during breathing and other forms of oxygen starvation, prolonged lactic acidosis.(A lack of oxygen, as you can see, also leads to acidosis, since in this case the oxidation is incomplete and the body cannot remove the incompletely oxidized reaction products.)

Short-term lactic acidosis occurs with increased muscular work, when the production of lactic acid increases and its insufficient oxidation occurs due to a relative oxygen deficiency.

excretory acidosis occurs as a result of a decrease in the excretion of non-volatile acids from the body in kidney diseases (chronic glomerulonephritis), leading to difficulty in the removal of acid phosphates, organic acids. The kidneys must remove 40-60 mmol of H + ions per day, which accumulate due to the formation of non-volatile acids. Excretory acidosis can also occur with long-term use of sulfa drugs, as there is an increased excretion of sodium ions in the urine.

Gastroenteric form of excretory acidosis can develop with a significant excretion of bases (alkalis) through the gastrointestinal tract, for example, with diarrhea, persistent vomiting, prolonged increased salivation.

exogenous acidosis occurs with a massive intake of acid-forming foods and acidic liquids and a lack of bases in foods, which is happening more and more often today.

With a normal acid-base balance, about half of the non-volatile acids are neutralized by the bases supplied with food, and the rest of the acids are neutralized by the buffer systems of the body.

Doctors in Germany are increasingly repeating the words: "Sie sind nicht krank - Sie sind ubersaueret", which means: "You are not sick - you are oxidized." This is not a disease yet, but a dangerous state of imbalance, the further development of which will soon lead to the development of serious diseases or the aggravation of existing ones.

The theory of body oxidation or exogenous acidosis and the explanation of the causes and complications of many diseases from these positions have recently become widespread in the West. According to this theory, more than 70% of the population in our time suffers from a violation of the acid-base balance, and from its shift to the acid side.

First of all, food products and ways of processing them are to blame for this. Almost 80% of the foods we eat are acid-forming. And it's not about how they taste. It's just that when they are broken down in the body, more acids are formed than alkalis (bases).

Acid-forming foods include beef, pork, lamb and chicken meat, sausage, white flour products, sugar, coffee, black tea, all alcoholic beverages, pasteurized juices, fish and seafood, cottage cheese, cheese, nuts and seeds, cereals, bread, buns and cakes, ice cream, eggs, lemonade, Coca-Cola.

The list could be continued, but it already looks quite impressive and sad.

But what about alkaline-forming foods?

Fruits (with the exception of canned ones), vegetables, herbs, natural yogurt, milk, soybeans, still mineral water, potatoes.

There is a clear predominance of acid products. This suggests that maintaining an acid-base balance in balance through nutrition alone is impossible for many - there is too much to give up. For most people, it is almost impossible to eat 3 kilograms of vegetables and fruits a day and exclude acid-forming foods: meat, cheese, sausage, sugar, coffee - not only the diet becomes poorer, but life is also boring. In addition, acid-forming foods are an important source of proteins, amino acids and vitamins, and drastically reducing their consumption or completely eliminating them from the diet means irreparable harm to the body.

What about the drinks we drink? What drinks dominate in our diet: acidic or alkaline?

pH of some foods

On fig. 14, 15 show products with the highest acidity.

Rice. fourteen. pH of 5% vinegar: 2.64

Rice. fifteen. Coke pH: 3.36

Please note that all measured liquids that we consume daily have an acidic pH. What efforts should be made every day to our body in order to maintain the acid-base balance in the norm! And where can he get the missing alkaline reserves?

The problem of changing the diet is becoming more and more acute for people who are trying to lead a more or less healthy lifestyle in the modern world. The popularity of industrially processed foods that have replaced "natural" food, the high caloric content of the diet, the content of a huge number of "lure" preservatives, dyes, flavors in products has led to the fact that food today has become not a source of minerals, vitamins, antioxidants necessary for a person, but a launcher. mechanism of many diseases.

In addition to food, the factors of modern life, almost or little seen before, are of great importance for the acidification of our body: chronic stress, medication, lack of physical activity, environmental pollution.

If the role of the first three factors, as a rule, is not denied, then when we talk about the danger of environmental pollution and its negative impact on health, we usually dismiss it. The connection between cement production and one's own health does not seem so obvious. In fact, this connection is direct. And it's not just about air pollution and an increase in the concentration of toxic substances in it. Transport waste, thermal power plants, coal and oil combustion and cement production lead to the formation of acid rain - a new phenomenon of our time that threatens human health. Rain is considered acidic if its pH is less than 5.

In the modern world, the excess acidity of rain is mainly due to the presence of two substances.

1. Sulfur oxides. These compounds are formed as a result of burning coal and oil containing small amounts of sulfur. In this case, sulfur in combination with oxygen enters the atmosphere. Dissolving in raindrops, sulfur oxides form sulfuric acid.

2. Nitrogen oxides. The main part of nitrogen oxides is formed when gasoline is burned in internal combustion engines (for example, in cars) or when coal is burned. When these substances are dissolved in raindrops, nitric acid is formed.

It is not very pleasant when sulfuric and nitric acids are dripping on you from the sky. Pictures that only science fiction writers came up with thirty years ago - rain that corrodes clothes and skin, when everyone who accidentally finds themselves under it rushes into a shelter in a panic - may become a reality tomorrow.

Acid rain destroys vegetation, oxidizes water bodies and soil.

However, the soil is acidified not only by acid rain, but also by numerous waste products from enterprises, including chemical ones, thrown into rivers and then deposited in the ground.

The danger of acidic soils is that the main nutrients (nitrogen, phosphorus, potassium) are inaccessible to plants in them. On the other hand, ions of manganese, iron, aluminum, heavy metals and radionuclides are available, which are consumed by plants in large quantities. Most plants do not feel very comfortable in an acidic environment: root growth is suppressed, immunity to pests and diseases is reduced, plants are not provided with minerals, nutrients, flavonoids, and vitamins in the required amount.

What plants do not receive, animals also do not receive, and doubly - people.

Therefore, the assertion that modern food is a source of “empty calories”, and not vitamins and minerals, has, unfortunately, soil under it, and soil is acidic.

Factors that cause body oxidation include food processing methods, deep freezing of meat, chemical pollination, and long-term transportation of vegetables and fruits.

What our ancestors ate fresh, having killed and roasted on a fire or picked from a tree, in terms of the quality of vitamins, minerals, active substances, of course, cannot be compared with what we get - by eating a piece of meat of the same size or that the same number of apples, traveling for weeks and months, for example, from Holland.

It is not surprising that in the modern world a person, having enough food, and often overeating, suffers from diseases associated with a lack of minerals and vitamins.

In America, a country far from food deficient, doctors at the Harvard School of Public Health in Boston, studying the health status of two thousand American and Canadian teenagers, concluded that approximately one third of them had a lack of nutrients, vitamins A and E, beta -carotene and omega-3 fatty acids. The lack of these substances has led, in particular, to a lower functionality of the lungs. Vitamin E deficiency increased the risk of asthma and omega-3 deficiency of chronic bronchitis.

A striking example of a disease caused by a lack of minerals is osteoporosis, a disease that is now considered one of the main causes of disability and death both in Russia and around the world.

The increase in cases of Alzheimer's disease is explained, on the one hand, by increased life expectancy, and on the other hand, by insufficient intake of vitamin B 3 in the body. This conclusion was made by American scientists working on this problem under the guidance of Dr. Martha Claire Morris from the Chicago Rush-Presbytrian-St. food. Even a small deficiency of this vitamin dramatically increased the risk of Alzheimer's disease.

Oxidation of the body for a long time is almost asymptomatic, but there are some signs, alarms, with which the body tries to draw attention to the growing imbalance.

Relatively early manifestations of oxidation include a decrease in the effectiveness of ongoing therapy for chronic diseases (increased tolerance to cardiac glycosides, antiarrhythmic drugs, some diuretics and other drugs).

Acidosis changes the biochemical properties of the blood, leads to a change in the speed of blood flow, aggregation (gluing) of red blood cells.

An increased load on the hemoglobin buffer of the blood causes changes in the rheopolyglutic properties and characteristics of the blood, a slowdown in blood flow, an increase in aggregation (gluing) of red blood cells, and a decrease in the supply of oxygen to tissues. This leads to the fact that the body does not receive enough nutrients, vitamins, oxygen, toxins are not removed from the cells. On fig. 16 clearly shows the changes in the blood caused by the oxidation of the body.

A real sensation was made in Germany by the recent researches of Dr. Irlacher, dedicated to the influence of living water on the properties of the blood and the treatment of conditions caused by or aggravated by oxidation with living water. For experiments, the technique of "black field", or phase-contrast microscopy, was used. You can judge the effectiveness of the use of living water from the photographs below (Fig. 17-19).

The last two photos especially show that the use of living water prevents blood clotting, which can contribute to the occurrence of strokes and heart attacks.

Our experience with the use of living water also shows the effectiveness of its use in patients with Raynaud's phenomenon and intermittent claudication (pain when walking), which is also quite obviously associated with improved blood circulation.

To regulate the acid-base balance, there are buffer systems(from English. buff- soften shocks), which bind an excess of hydrogen ions and control their further movement in the body. They are chemical compounds that have amphoteric properties, that is, compounds that behave like bases in an acidic environment, and like acids in a basic one. If there were no buffer systems, acidic metabolic products formed during the decomposition of acid-forming products, when they enter the bloodstream, would lead to a shift in pH to the acid side and to instant death. So, for example, with intense muscular activity, up to 80-100 g of lactic acid can enter the human blood within a few minutes. If this amount of lactic acid is added to 6 liters of distilled water (the volume of circulating blood in a person weighing 70 kg), then the concentration of H + ions will increase by 40,000 times. Thanks to buffer systems, the reaction of the blood under these conditions practically does not change.

With excessive intake or formation of acids, the body experiences a constant need for alkaline reserves. The most important of them are minerals: sodium, potassium, calcium, magnesium. If insufficient alkaline-forming products enter the body with food (and they just do not get enough!), then the body turns to internal reserves and exchanges mineral ions for H + ions. At the same time, the first relatively "harmless" signs of chronic oxidation of the body develop. So, when minerals are taken away from the scalp, hair loss begins, when teeth are demineralized, periodontal disease occurs, when calcium ions are “borrowed” from bones, osteoporosis develops.

On average, a person loses 40-100 hairs a day. The causes of hair loss are different, but in all cases (with the exception of hormonal and hereditary), a lack of minerals and vitamins plays a special role. In a normal state, the scalp is rich in bases - minerals. When the body is acidified and minerals are borrowed from the hair, their loss is observed. Therefore, hair loss is often the body's first signal of a violation of the acid-base balance.

From our experience: the following complex helps with hair loss. Drinking 1 glass of living water daily and rinsing the head with living water after washing. To prepare catholyte for drinking, tap water is poured into the apparatus and activated for 10 minutes. Drink 150-200 ml 3 times a day. To rinse the hair, hot water is poured into the apparatus, 1/3 teaspoon of salt is added to the anode zone of the apparatus (inner container), activated for 13 minutes. Catholyte is used for rinsing the head after washing and rubbing into the scalp. After applying catholyte, it is not recommended to dry your hair with a hairdryer.

Osteoporosis has been called a "fragile epidemic". With this disease, the bones lose their strength, their bone mass decreases, they become thinner, brittle and brittle. But the bone is the most durable element in the body. So, for example, it is known that a healthy femur can withstand a load of up to 1.5 tons! Today, osteoporosis is one of the main causes of disability and mortality both in Russia and around the world. According to the World Health Organization, osteoporosis ranks fourth among non-communicable diseases after diseases of the cardiovascular system, oncological pathology and diabetes mellitus.

The main reasons for the development of osteoporosis are considered to be the loss of the organic base and minerals of calcium, magnesium and phosphorus with low activity of cells that produce bone tissue. Risk factors include menopause, decreased calcium intake, and impaired absorption of calcium in the gastrointestinal tract. The development of osteoporosis is counteracted by vitamin D, which is produced in the skin under the influence of solar radiation. It would seem that everything is quite simple: you need to make up for the lack of these minerals and vitamin D, to be more in the sun. However, osteoporosis is very difficult to cure.

The theory of chronic oxidation of the body logically and quite convincingly explains this as follows: the oxidation of the body leads to the fact that minerals do not get to the bones, but are spent on more urgent purposes - neutralizing acids and replenishing the buffer systems of the body, therefore even a massive introduction of minerals has little effect on the course of the disease . In addition, when the acid-base balance shifts to the acid side, the removal of minerals from the bones will continue.

The Japanese doctor, scientist, MD Ishitani proved that the normalization of the acid-base balance and the simultaneous intake of minerals lead to a much better result in the treatment of patients with osteoporosis.

The method of using catholyte in the treatment of osteoporosis.

For our part, we have also observed an increase in bone mass and a decrease in bone fragility with the simultaneous intake of living water and ionized minerals. In osteoporosis, it is recommended to drink catholyte prepared on the basis of tap water with the addition of 10 ml of a 10% calcium chloride solution to the anode zone. Activate 7 minutes. It is necessary to drink water of the cathodic zone for at least a month (if necessary, longer), after meals, 200 ml 3 times a day.

Nerve endings that are outside the cells are very sensitive to changes in pH. With mechanical or thermal damage to tissues, the cell walls are destroyed and their contents enter the nerve endings. As a result, the person feels pain. Scandinavian researcher Olaf Lindal did the following experiment: using a special needleless injector, a very thin stream of a solution was injected through the skin of a person, which did not damage the cells, but acted on the nerve endings. It has been proven that hydrogen cations cause pain, and with a decrease in the pH of the solution, the pain intensifies.

You can find out if your body is suffering from oxidation as follows.

1. After analyzing how you feel and determining if you have the above symptoms or diseases.

2. Passing a urine test.

3. By measuring the pH of saliva and/or urine on your own.

Two methods are generally used to determine the pH value.

1. Hydrogen index can be determined using indicators that change color depending on the acidity of the medium. The most well-known are litmus tests. They change their color, which is compared with the color of the pH scale, where each color corresponds to a specific pH value.

2. For more accurate pH measurements, special devices are used - a pH meter or an ion meter, which measure pH more accurately (up to 0.01 units). The method is convenient and highly accurate; it allows measuring the pH of opaque and colored solutions and is therefore widely used.

If the redox potential index characterizes the redox qualities of a solution (juice, water, human) from an electrochemical point of view, then the pH index - from a biochemical one.

There is a relationship between redox potential and pH. It is expressed in the fact that when the pH of drinking water changes by one by adding alkali or acid, the redox potential of the solution changes by about 59 mV.

Urine pH measurement

Urine pH measurements should be carried out within a week. To correctly evaluate the results obtained, you need to know that the pH of urine depends on nutrition, mental state, time of day. Normal urine pH ranges from 4.5 to 7.7.

The difference between the pH of urine in the morning and afternoon is characteristic of a healthy body. In the second half of the night, more acids should be released, so the urine should be more acidic in the morning than in the evening. If the acid-base balance is disturbed, fluctuations in the acidity of urine become hardly noticeable or disappear altogether. At the same time, both in the morning and in the afternoon, acidic urine is excreted, or acidic and neutral, but without an alkaline phase.

Each person has individual fluctuations in the pH of urine, but it is important that there is a difference between the pH of night, morning and daytime urine. It is necessary to measure the pH of urine not at the beginning of urination, but in the middle.

Saliva pH measurement

Unlike urine pH values, which depend on many factors, saliva pH is one of the most unaffected factors. The pH of saliva in a healthy person is in the range of 6.0–7.9. Values ​​less than 6.0 indicate the oxidation of the body. Saliva pH measurement should be carried out as follows: collect more saliva and put litmus paper under the tongue for about 1 minute, then compare the color of the indicator with the color chart.

Living water is an affordable and simple method of maintaining a balance between acid-forming and alkaline-forming products. An exception among many liquids, living water has a pH of 7 to 12, depending on the degree of activation.

The method of using catholyte for the correction of acid-base balance. Daily consumption of 200 to 500 ml of activated alkaline (live) water, prepared in a tap water machine for 10 minutes, can serve as a counterbalance to the acid-producing foods and drinks prevailing in the diet, as well as an excellent antioxidant defense.

Living water is an active unstable system, which after a while loses its biochemical and (partially) medicinal properties.

For living water, there is a direct dependence of medicinal properties on the values ​​of redox potential and pH. But if the pH value is maintained for a long time (months), then the redox potential of living water returns to its original value within 2 days, provided that it is stored in a closed vessel in a dark place. This makes the process of drinking living water dependent on the presence of the apparatus.

The best way to drink living water: done - drank.

True, in Germany we managed to extend the therapeutic effect of living water up to a month, but this requires additional rather expensive equipment.

The situation is different with dead water (anolyte). Its biochemical characteristics and properties (anti-allergic, anti-inflammatory, antiseptic) are preserved for a long time (up to six months) under proper storage conditions.
