Buffer capacityHardQuestion 600441

Question

Among the following, which buffer has the highest capacity?
  1. A
    0.01 M each of HA and A⁻
  2. B
    1 M each of HA and A⁻
    Correct
  3. C
    0.1 M each of HA and A⁻
  4. D
    0.001 M each

Correct answer

1 M each of HA and A⁻

Explanation

Buffer capacity is proportional to the concentrations of both acid and conjugate base. Higher total concentration → higher capacity to resist pH changes. 1 M each gives maximum capacity here.
