WebIn strong acid-weak base titrations, the pH at the equivalence point is not 7 but below it. This is due to the production of a conjugate acid during the titration; it will react with water to produce hydronium (H 3 O +) ions. In the example of the titration of HCl into ammonia solution, the conjugate acid formed (NH 4+) reacts as follows:
