Acetic acid (CH3COOH) is a weak acid, and acetate ion (CH3COO-) is a weak base. Together, acetic acid and acetate ions form a conjugate acid-base pair. In solution, this conju â¦ gate acid-base pair act as a buffer solution.When small amounts of acid or base are added, buffer solutions are able to resist changes in pH.here are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, â¦ the bicarbonate buffer system is the most predominant. Buffer Systems function as shock absorbers that accept excess H+ ions or OH-ions and keep blood pH constant.
