Q. The Ostwald dilution law is expressed as
A) $K_{a} = \frac{C\alpha^{2}}{(1 - \alpha)}$
B) $K_{a} = \frac{C\alpha}{(1 - \alpha)}$
C) $K_{a} = \frac{1 - \alpha}{C\alpha^{2}}$
D) $K_{a} = \frac{C(1 - \alpha)}{\alpha^{2}}$
Explanation
(a)
Ostwald dilution law is :
$K_{a} = \frac{C.\alpha^{2}}{(1 - \alpha)}$
Where,
$K_{a} =$ dissociation constant
$\alpha =$ degree of dissociation
$C =$concentration
