Answer. The concentration of hydrogen ions in solution 

The formula for pH is  pH = -log[H+]. This means pH is the negative base 10 logarithm of the hydrogen ion concentration of a solution.

The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
