pH stands for Hydrogen potentials or historically denoting "potential of hydrogen". It refers to the concentration of the hydrogen ions in a solution. It’s a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic solutions. This is the indicator of a solution's acidity or alkalinity. On a pH scale, the pH value ranges from 0 to 14.
