Which statement about buffer capacity is correct?
A.It increases with the total buffer concentration
B.It depends only on the ratio [A⁻]/[HA]
C.It is highest far from the pKa
D.It is independent of concentration
Explanation
Core Concept
More HA and A⁻ available means more acid/base can be absorbed before the ratio (and pH) changes much. Concentration, not just the ratio, sets capacity.
Correct Answer
AIt increases with the total buffer concentration
