Buffers are designed to resist drastic changes in pH when small amounts of acid or base are added to a solution. This is because they consist of a weak acid and its conjugate base (or a weak base and its conjugate acid), which can neutralize small amounts of added acid or base, thereby maintaining the pH at a nearly constant value.
