Question

Quizplus · Accepted Answer

A buffer is a substance that can resist changes in pH by either accepting or releasing hydrogen ions. This property allows buffers to maintain a relatively constant pH despite changes in the environment.

Salts do not necessarily have any special properties related to pH resistance.
