WebMost buffer solutions contain a weak acid and its corresponding base, which combine reversibly with hydrogen ions. In the example provided, carbonic acid is the H+ donor, and bicarbonate is the H+ acceptor. The reaction tilts to the right and creates more H+ as the pH rises. It tilts to the left and accepts more H+ as pH falls. WebA buffer is any system that will resist changing pH when materials are added. When pH = pKa your ratio of [HA]/ [A-] = 1. [A-] will resist the pH going down by absorbing protons while [HA] will resist the pH going up by donating protons. At [HA]/ [A-] = 1 you have the largest amount of buffering molecules in either direction.
