In chemistry, the degrees of acidity of alkalinity of a substance are expressed in PH values. The neutral point, where a solution would be neither acid nor alkaline is PH 7. Increasing acidity is expressed as a number less than 7, and increasing alkalinity is a number greater than 7. 从中...
pH,range of numbers expressing the relative acidity or alkalinity of a solution. In general,pH values range from 0 to 14. ThepH of a neutral solution, i.e., one which is neither acidic nor alkaline, is 7. Acidic solutions havepH values below 7; alkaline, or basic, solutions havepH va...

Whenever your pH levels start falling, your body makes a natural attempt of self regulation to enter homeostasis. It will do so through the capture and storage of all the acidic substance within your organs, especially liver, lungs and kidneys. It attempts to bring the overall pH to between ...
