Suppose you have a bottle of acetic acid and a bottle of sodium acetate, CH₃CO₂Na, and you add some of each to the same beaker of water. Consult Tables 15.5 and 15.6 to help you answer the following questions.

(a) Is there a weak acid in the beaker? If so, what is it?

(b) Is there a weak base in the beaker? If so, what is it?

(c) Is there a conjugate pair in the beaker? If so, what is it?
