Buffer solution pairs

WebA buffer solution is a solution of a weak acid or base with its conjugate pair that can resist changes in pH when a small amount of strong acid or base is added. Buffer solutions are made by mixing a weak acid or base with a large amount of its conjugate pair, even so that there is equal amounts of both. WebBuffers do so by being composed of certain pairs of solutes: either a weak acid plus a salt derived from that weak acid or a weak base plus a salt of that weak base. For example, a buffer can be composed of dissolved HC 2 H 3 O 2 (a weak acid) and NaC 2 H 3 O 2 (the salt derived from that weak acid).
