Answer 1

Answer:

The best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"

Explanation:

A buffer is a solution that is somewhat resist to pH changes by reacting with acids and bases that may be added into the solution. It's capacity is the amounto of acid or base that can be added into solution without much change in pH.

So the best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
