WebThe conjugate base of a strong acid would be an exceedingly weak base and so it would be severely limited in neutralizing additional acid. Essentially the addition of more acid would lower the pH even more so. The purpose of a buffer is to resist these drastic changes in pH so a strong acid buffer wouldn't really be achieving that.

WebJul 27, 2024 · By doubling the total molar concentration of the buffer system will double the capacity of buffer at a given pH. Buffer can also be increased by using equimolar concentrations of the acid (HA) and its conjugate base (A – ). The buffer has its greatest capacity, when ratio [salt]/ [acid] are equal to 1, i.e. [HA] = [A – ].
