The pH of sodium bicarbonate solution depends on

The pH of sodium bicarbonate solution depends on

A
the ionization constant of $H_{2} {CO}_{3}$
B
the ionization constant of ${HCO}_{3}^{-}$
C
the ionization constants of both $H_{2} {CO}_{3}$ and ${HCO}_{3}^{-}$
D
the concentration of sodium bicarbonate

Solution:

For a salt such as ${NaHCO}_{3}$ , pH of the solution is given by

$pH = \frac{1}{2} (p K_{a 1}^{\circ} + p K_{a 2}^{\circ})$

where $K_{al}$ and $K_{a 2}$ are the ionization constants of $H_{2} {CO}_{3}$ and ${HCO}_{3}^{-}$ , respectively
