GlossaryHydrogen Ion Concentration

measures acidity or alkalinity of a solution

Hydrogen Ion Concentration, often referred to as H+ concentration, measures the number of hydrogen ions present in a solution. It is a critical factor in determining the acidity or alkalinity of a substance, commonly expressed as pH. A higher H+ concentration indicates a more acidic solution, while a lower concentration indicates a more basic or alkaline solution. This concept is essential in various fields, including chemistry, biology, and medicine, as it affects biochemical reactions and processes.
