How to Make a Phosphate Buffer Solution

The goal of a buffer solution is to help maintain a stable pH when a small amount of acid or base is introduced into a solution A phosphate buffer solution is a handy buffer to have around especially for biological applications Because phosphoric acid has multiple dissociation constants you can prepare phosphate buffers near any of the three pHs which are at 2 15 6 86 and 12 32
