There are certain acids that will not ionize very easily when added to water. These acids will only give up there protons to water with difficulty.
Weak acids can exhibit low pH readings just as strong acids.
Acid strength of weak acids has more to do with the ionization constant of the acid. Consequently, they form an equilibrium with their ions.

The ionization constant of a monoprotic acid, HA, is 2 X 10 -10 .
