The titration of a strong acid by a strong base gives sharper and more well-defined end points than titration of a weak acid by a weak base.

Question

Quizplus · Accepted Answer

In a strong acid-strong base titration, the pH changes rapidly near the equivalence point, resulting in a sharp and well-defined endpoint. In contrast, weak acid-weak base titrations have a more gradual pH change, making the endpoint less distinct.
