How to Make a Phosphate Buffer Solution - ThoughtCo

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.
