A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an acid or a base aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. (wikipedia.org)
Buffer solutions resist pH change because of a chemical equilibrium between the weak acid HA and its conjugate base A−: HA ⇌ H+ + A− When some strong acid is added to an equilibrium mixture of the weak acid and its conjugate base, hydrogen ions (H+) are added, and the equilibrium is shifted to the left, in accordance with Le Chatelier's principle. (wikipedia.org)
Once the acid is more than 95% deprotonated, the pH rises rapidly because most of the added alkali is consumed in the neutralization reaction. (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)

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 negligible when the concentration [HA] of buffering agent is very small and increases with increasing concentration of the buffering agent. (wikipedia.org)
