A buffer solution will become much more acidic when even a small amount of a strong acid is added.

Question

Quizplus · Accepted Answer

A buffer solution resists changes in pH when small amounts of acid or base are added. This is because it contains both a weak acid and its conjugate base in roughly equal amounts. Adding a strong acid to a buffer solution will cause the weak acid to react with the added acid, but the conjugate base will react with any protons that are released, preventing a significant change in pH. However, if a large amount of strong acid is added, the buffer will eventually be overwhelmed and the pH will decrease significantly.
