A buffer is capable of reducing the effect of the addition of small amounts of hydronium or hydroxide ion to a solution.

Question

Quizplus · Accepted Answer

A buffer solution resists changes in pH when small amounts of acid (hydronium ions, H3O+) or base (hydroxide ions, OH−) are added. This is due to the presence of a weak acid and its conjugate base (or a weak base and its conjugate acid) in the buffer, which neutralize the added ions.
