pH calculator for both strong and weak (Monoprotic) acids

This CalcTown calculator calculates the pH of any solution given its concentration.

* For a strong acid (~>0.001 M) which completely dissociates in aqueous medium, concentration of Hydronium ions is equal to the concentration of the acid. For weaker acids, dissociation is a reversible process and hence, the concepts of equilibrium has to be considered.

**If the acid is strong, enter 0 in the fields "Ka".
