At what pH does a buffer solution exhibit maximum buffer capacity?

Answer 1

At #pH=pKa#

Since the acidic and basic components of the buffer systems are equally concentrated at this pH, it will be easier for this solution to withstand abrupt pH changes when small amounts of acids and alkali are added.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
