Buffer solution pairs
WebTo generate a buffer solution, you need a weak acid and its conjugate base or a weak base and its conjugate acid in nearly equal molar ratios. Based on this information, let's examine the pairs of substances given: 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.
