FREE Expert Solution

Recall that a buffer can be composed of the following:

weak base and its conjugate acid
weak acid and its conjugate base
weak acid and a strong base 

▪ concentration of weak acid > concentration of strong base

weak base and a strong acid 

concentration of weak base > concentration of strong acid
