 A buffer resists pH change by neutralizing added acids and bases.

Explanation:

Buffer is a solution which can resist the change in pH with small addition of acid or base.

Buffer solution is the solution which resists the change in the magnitude of the pH when small additions of either acid or base is adde. Buffer neutralises the added acid or base and hence prevent the change in pH.

Buffer solutions consist of weak acid and its conjugate base usually which are mixed in relatively equal and large quantities.

Two strong bases will not form a buffer.

Hence a buffer resists pH change by neutralizing added acids and bases.
