Question

Buffer capacity of a buffer will be maximum when

$pH = pK_a - 1$

$pH = pK_a + 1$

$pH = pK_a$

pH= zero

Answer

$pH = pK_a$

Explanation

Solution

Buffer capacity of a buffer is maximum when the concentration of the weak acid and its salt or weak base and its salt are equal i.e., when ${pH = pK_{a}}$ or ${pOH = pK_{b}}$ .
