Establish the proper buffer pairs and analyze each choice if they are possible buffer pair

Step 1. Recall that buffers resist drastic changes to the pH if a strong acid or strong base is added.

A buffer is a solution that can be made up of:

• weak base and its conjugate acid
• weak acid and its conjugate base
