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 = pKa or pOH = pKb.

Q. Buffer capacity of a buffer will be maximum when

$p H = p K_{a} - 1$

$p H = p K_{a} + 1$

$p H = p K_{a}$

pH= zero

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 $p H = p K_{a}$ or $pO H = p K_{b}$ .

Q. Buffer capacity of a buffer will be maximum when

pH=pKa​−1

pH=pKa​+1

pH=pKa​

pH= zero
