Question

For the basic buffer solution the pH is 9.3. The pH can be increased by: (A) increasing the concentration or me sail g (B) increasing the concentration of the base (C) decreasing the concentration of the base (D) decreasing the Kb value of the base

The pOH of a basic buffer solution is given by Handersons equation pOH=pKb+ log ([salt]/[base]) This equation shows that increase in concentration of base will decrease pOH ie., will increase pH (pH = 14 - pOH).

Q. For the basic buffer solution the pH is 9.3. The pH can be increased by:

increasing the concentration or me sail g

increasing the concentration of the base

decreasing the concentration of the base

decreasing the $K_{b}$ value of the base

The pOH of a basic buffer solution is given by Handersons equation $pO H = p K_{b} + lo g \frac{[ s a lt ]}{[ ba se ]}$ This equation shows that increase in concentration of base will decrease pOH ie., will increase pH (pH = 14 - pOH).
