"Buffer solutions resist pH change because of a chemical equilibrium between the weak acid HA and its conjugate base 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. Because of this, the hydr… " - Region of maximum buffering
