What is a solution that reacts with both acids and bases to maintain a constant pH called?

Question

Quizplus · Accepted Answer

A buffer is a solution that can resist changes in pH when small amounts of acid or base are added. It works by containing a weak acid and its corresponding conjugate base, or a weak base and its corresponding conjugate acid, that react with H+ or OH- ions to maintain a relatively constant pH. Buffers are essential for many biological processes, such as regulating blood pH and maintaining enzyme activity. Lipids are a class of organic molecules that are not related to pH regulation. Barriers and liquids are not specific enough to describe a solution that can resist changes in pH.
