Question

State Ostwald's dilution law.

Answer 1

Ostwald's dilution law relates the dissociation constant of the weak electrolyte with the degree of dissociation and the concentration of the weak electrolyte.
$K_a=\frac{{\alpha }^{2}c}{1-\alpha }$
$K_a$=dissociation constant of weak acid
$\alpha =$ degree of dissociation.
Ostwald's dilution law states that the weak electrolyte undergoes complete ionisation at infinite dilution only.
