pH values can be used to find the hydrogen ion concentration of a solution.

Some examples:
A 0.1M HCl solution contains 0.1 mol/L hydrogen ions
the pH can be calculated by the following relationship...
pH = -log(H+) = -log(0.1) = 1

A 0.01M HCl solution contains 0.01 mol/L hydrogen ions
the pH can be calculated using...
pH = -log(0.01) = 2

Here are some added examples:
