Buffer solution pairs
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).

WebFeb 18, 2015 · A buffer solution is prepared by mixing a weak acid (or base) with a strong salt of that acid For example you can prepare the following buffer in two ways: H O A c + N a O A c 1: Mixing directly a solution of the salt with the acid 2: Adding (let's say dropwise) a solution of N a O H to the acid. In this case N a O A c will be formed in situ. Web6.2 – Buffer Solutions. . Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added (Figure 6.2.1).
