WebA buffer is an aqueous solution containing a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer's pH changes very little when a small amount of strong acid or base is added to it. It is used to prevent any change in the pH of a solution, regardless of solute. 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).

WebMar 9, 2024 · Examples of Buffer Solutions. Buffer solutions always contain two components – a weak acid or base and its conjugate. Buffers are therefore considered conjugate acid-base pairs. This means one acts as a proton (H +) donor and the other as a proton acceptor. However, not all conjugate acid-base pairs make useful buffers.
