When the pH of the solution is equal to the pKa of the ionizing group, the solution is functioning at maximum buffering capacity (best buffer). An aqueous solution of a conjugate acid/base pair functions as a good. buffer when the ratio of the conjugate base to weak acid ranges from 1:9. to 9:1.
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.
