WebMar 30, 2024 · It happens even without presence of any buffering substance, aside of strong acids or bases. If an acid, monoprotic or diprotic, is added, a peak(s) of maximum buffer capacity is added. But if $\mathrm pK_\mathrm a$ is small, the peak of maximum buffer capacity does not lay on a steady baseline of the capacity function. It lays on a … Web• To determine the buffer capacity of a specific buffer solution. • To determine the effect of dilution on the buffer’s ability to resist pH changes and its buffering capacity. • To design a buffer system at a given pH which is the most effective in resisting pH changes (has the greatest buffering capacity).
