WebBuffer capacity is defined as the number of moles of acid or base that have to be added to 1 liter to cause its pH to change by 1 unit. As a formula this is: B = n/ΔpH, where B is buffer capacity (which is unitless), n is the number of moles of acid or base that was added to … 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). easiest chicken soup
