Question
Consider the benzoic acid/sodium benzoate buffer described in the previous problem. If NaOH is added to this buffer, which of the following changes will occur?
A. [benzoic acid] will decrease and [sodium benzoate] will increase.
B. [benzoic acid] will increase and [sodium benzoate] will stay the same.
C. [benzoic acid] will stay the same and [sodium benzoate] will decrease.
D. [benzoic acid] will stay the same and [sodium benzoate] will increase.
E. [benzoic acid] will decrease and [sodium benzoate] will stay the same.
Explanation / Answer
if you add a base, the conjugate base will increase, the acid will decrease (will get neutralized)
then
A. [benzoic acid] will decrease and [sodium benzoate] will increase.
