The sodium salt of a weak acid is hydrolysed to the extent of 3% in 0.1 M solution in water at $25 ° C$ . If $K_{a}$ for weak acid is $1.3 \times 1 0^{- 10}$ . The ionic product of water is

Options:

Answer:

Solution:

$K_{H} = α^{2} C$
$[_{hydrolysis}^{α = degree of}]$
$= (0.03)^{2} \times 0.1 = 9 \times 1 0^{- 5}$
$K_{H} = \frac{K_{w}}{K_{a}}$
or $K_{w} = K_{H} \times K_{a}$
$= 9 \times 1 0^{- 5} \times 1.3 \times 1 0^{- 10}$
$= 1.17 \times 1 0^{- 14}$ .
