Webcapacity is a quantitative measure of the resistance of a buffer solution to change in pH on addition of strong acid or base. Normally it can be defined as the millimoles of strong acid or base required to change the pH of 1 liter of buffer by ±1.0 unit. Buffer capacity is related to the concentrations of base and acid components.
