A buffer is a mixture of molecules that release or bind H+ in order to maintain a relatively stable pH. Note that the function of a buffer is NOT to keep a solution neutral (at pH 7); its function is to minimize the change in pH when base or acid is added to the solution. Also note that there are many different buffers, and each one will stabilize the pH of a solution only within a specific pH range.
