What does pH mean?

PH value, also known as pH value, was advocated by Danish biochemist Serenshan (1868~ 1939), and it is an indicator of "hydrogen ion concentration in solution". Use Gaussian electrode and measure with "acidity meter". Or 2-3 drops of color, to determine its concentration. There are a lot of chemical reactions in the human body, and the pH of its body fluids can naturally be measured by pH value. The pH index is displayed as a number between 0 and 14. At room temperature (25℃), the middle 7 is neutral. The greater the value, the greater the alkalinity and the smaller the value.

Meaning of pH value:

PH value is the pH value of chemical solvent, which is used to indicate the pH value of solution to judge whether the solution is acidic, neutral or alkaline. With test paper, the more the value tends to 0, the stronger the acidity, the more it tends to 14, the stronger the alkalinity, and 7 is neutral. At standard temperature (25℃) and pressure, the pH value of pure water is 7.

Generally speaking, pH value is an indicator of the intensity of chemical reaction. The higher the pH value of alkaline solvent, the greater the intensity of chemical reaction. According to relevant data, every time the pH value is different by one value, the hydrogen ion concentration is different by 10 times, that is, every time the pH value is different by one value, its acidity or alkalinity is different by 10 times.
