FREE Expert Solution

We are being asked to determine which of the following combinations cannot produce a buffer 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
