Ph measures the concentration of hydrogen ions (h⁺) in a solution and indicates whether a solution is acidic, neutral, or basic The ph scale typically ranges from 0 to 14, where 7 is neutral, values below 7 are acidic, and values above 7 are basic (alkaline). A ph value is the quantitative measure of the acidity or basicity of aqueous or other liquid solutions The term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion into numbers between 0 and 14.
