Vedclass · Answer

(B) According to Ostwald's dilution law,the degree of dissociation $(\alpha)$ of a weak electrolyte is related to the concentration $(C)$ by the expression $\alpha = \sqrt{\frac{K_a}{C}}$.Thus,the degree of dissociation is inversely proportional to the square root of the concentration of the electrolyte.Therefore,decreasing the concentration of the electrolyte increases the degree of dissociation.

Electrolytes when dissolved in water dissociate into their constituent ions. The degree of dissociation of an electrolyte increases with
