WebSep 9, 2024 · The pH scale is a familiar concept for students who study science. The pH value of a solution reflects the relative concentration of hydrogen ions (H+) or protons to the concentration of hydroxide ions (OH-) in a solution. Solutions with a pH value less than 7 are acidic and those with a value greater than 7 are basic, or alkaline. WebpH = −log ([H +]) The formula for pH is shown above. pH is defined as the negative log base 10 of the hydronium concentration.
