Does pH change with dilution?
Asked by SHAMLI RAUT | 11th Jul, 2013, 11:51: PM
pH is generally calculated the negative log of the hydrogen ion concentration in solution.
If you dilute an acidic solution (with water), you lower the [H+] concentration, and
if you dilute a basic solution you increase the [H+].
You could also think of it as the [H+] concentration in both cases approaching the [H+] concentration of pure water (pH ~7).
So the pH of an acid will increase and the pH of a base will decrease.
