WebBuffers typically consist of an acid-base pair, with the acid and base differing by the presence or absence of a proton (a conjugate acid-base pair). For instance, one of the buffers that maintain the pH of human blood involves carbonic acid (H _2 2 CO _3 3) and its conjugate base, the bicarbonate ion (HCO _3 3 ^- − ). WebApr 21, 2016 · Why does a buffer work best at the $\mathrm{pH}$ closest to its $\mathrm{p}K_\mathrm{a}$? ... You need the weak base to react with added acid, and the weak acid to react with added base to stabilize the pH. When the pH is very different from the pKa, one of those two species will be at very very low concentration (there is an …
