The pH changes relatively slowly in the buffer region, pH = pKa ± 1, centered at pH = 4.7, where [HA] = [A−]. The hydrogen ion concentration decreases by less than the amount expected because most of the added hydroxide ion is consumed in the reaction OH− + HA → H2O + A− and only a little is consumed in the neutralization reaction (which is the reaction that results in an increase in pH) OH− + H+ → H2O. (wikipedia.org)
Buffer capacity is a quantitative measure of the resistance to change of pH of a solution containing a buffering agent with respect to a change of acid or alkali concentration. (wikipedia.org)
