WebIt is a measure of the resistance of a buffer solution to pH change on the addition of hydroxide ions. Buffer capacity differs in accordance with the core components of the buffer solution and the amount of strong acid or base. If adding a strong acid to buffer solutions, the capacity is equal to the base’s amount.
