Increases with dilution.

Vedclass · Answer

(B) According to Ostwald's dilution law,the degree of dissociation $\alpha$ for a weak electrolyte is given by the formula $\alpha = \sqrt{\frac{K_a}{C}}$,where $K_a$ is the dissociation constant and $C$ is the molar concentration. Since $C = \frac{n}{V}$,where $V$ is the volume of the solution,we have $\alpha = \sqrt{K_a 	imes V}$. As the dilution increases,the volume $V$ increases,which leads to an increase in the degree of dissociation $\alpha$.

For a weak electrolyte,the degree of dissociation $\alpha$ is:
