A chemical buffer system enables a solution to resist a marked change in pH upon addition or loss of acid or base.

Question

Quizplus · Accepted Answer

A chemical buffer system is composed of a weak acid and its corresponding conjugate base or a weak base and its corresponding conjugate acid. When an acid or base is added to the system, the buffer reacts to prevent a significant change in pH by either accepting or donating protons. This allows the solution to resist a marked change in pH, making it an effective way to maintain stable pH levels in biological and chemical systems.
