PH is the hydrogen index, (from the Latin words "potentia hydrogeni" is the force of hydrogen, or "pondus hydrogenii" is the weight of hydrogen) - the activity measure (in the case of dilute solutions reflects the concentration) of hydrogen ions in solution, quantitatively expressing its acidity, is calculated as negative (taken from The decimal logarithm of the concentration of hydrogen ions, expressed in moles per liter: pH = -log [H +]. Those. The pH is determined by the quantitative ratio in water of the H + and OH- ions formed during the dissociation of water. (Mole is a unit for measuring the amount of a substance.)
If in water the reduced content of free hydrogen ions [H +] (pH> 7) in comparison with ions of [OH-] hydroxide, then water will have an alkaline reaction, and with an increased content of H + (pH <7) - acid. In ideally pure distilled water these ions will balance each other and in neutral water pH = 7. When dissolving various chemicals in water, this balance can be disturbed, which leads to a change in the pH value.
When the concentrations of both types of ions in the solution are the same, it is said that the solution has a neutral reaction. When the acid is added to the water, the concentration of hydrogen ions increases, and the concentration of hydroxide ions decreases accordingly, when the base is added, on the contrary, the content of hydroxide ions increases, and the concentration of hydrogen ions decreases. When [H +]> [OH-] it is said that the solution is acidic, and at [OH-]> [H +] - alkaline.
The body balances the pH of internal fluids, maintaining values at a certain level. The acid-alkaline balance of the body is a certain ratio of acids and alkalis in it, which contributes to its normal functioning. The acid-base balance depends on the preservation of relatively constant proportions between the intercellular and intracellular waters in the tissues of the body. If the acid-base balance of fluids in the body is not maintained constantly, normal functioning and preservation of life will be impossible.
According to Japanese researchers, drinking water with a pH above 6.5-7 increases the life expectancy of the population by 20-30%.
Acidic environment in the body provokes a lot of diseases and promotes the vital activity of parasites. Parasites prefer an acidic habitat, and it is in the acidic environment that they manifest themselves most pathogenically. Sour environment is created by mental and physical overloads, meat food, and food that has undergone a deep thermal and other technological treatment, reducing the content of useful substances in it. These same sources of acidification fill the body with free radicals, which overload the immune system.
