State Ostwald's dilution law.

(N/A) Ostwald's dilution law states that for a weak electrolyte,the degree of dissociation $(\alpha)$ is inversely proportional to the square root of its concentration $(C)$.
Mathematically,it is expressed as: $\alpha = \sqrt{\frac{K_a}{C}}$,where $K_a$ is the dissociation constant of the weak acid.
As the dilution increases (concentration $C$ decreases),the degree of dissociation $\alpha$ increases,approaching unity at infinite dilution.
