PH, 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. Learn more about pH.

Acidosis, defined by blood pH below 7.35, is the most common disorder of acid–base homeostasis and occurs when there is an excess of acid in the body. In contrast, alkalosis is characterized by excessively high blood pH.
4 Ιαν 2024 · pH stands for Potential of Hydrogen, which simply means the power of hydrogen in a compound. pH value helps determine the nature of the solution. It helps to define the acidity and basicity of a solution. pH value should be balanced for the proper well-being of the environment and living organisms.
30 Ιαν 2023 · pH indicators are weak acids that exist as natural dyes and indicate the concentration of H + (\(H_3O^+\)) ions in a solution via color change. A pH value is determined from the negative logarithm of this concentration and is used to indicate the acidic, basic, or neutral character of the substance you are testing.
13 Μαΐ 2024 · The pH scale shows the acidity, neutrality and alkalinity of chemicals. pH = -log [H+] where [H +] is the concentration of hydrogen ions in mol dm –3. [H+] = 10-pH. HA (aq) → H+ (aq) + A- (aq) What is the pH of 0.01 mol dm -3 hydrochloric acid? pH values should always be to two decimal places. Sign up now. It’s free!
6 Μαΐ 2019 · pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic. pH of 7 is considered neutral (e.g., pure water). Typically, values of pH range from 0 to 14, although very strong acids may have a negative pH, while very strong bases may have a pH exceeding 14.
