A chemical buffer system is a mixture in a solution of two chemical compounds that minimize pH changes when either an acid or a base is added to or removed from the solution.

Question

A chemical buffer system is a mixture in a solution of two chemical compounds that minimize pH changes when either an acid or a base is added to or removed from the solution.​

Quizplus · Accepted Answer

This statement is true. A chemical buffer system works by absorbing or releasing hydrogen ions (H+) to prevent the pH of a solution from changing too dramatically when an acid or base is added. The two chemical compounds in the buffer system work together to maintain a stable pH. Examples of biological buffer systems include bicarbonate/carbonic acid and phosphate.
