FREE Expert Solution

We’re being asked to determine which of the pairs cannot be mixed together to form 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
