on increasing dilution

Vedclass · Answer

(C) According to Ostwald's dilution law,the degree of dissociation $(\alpha)$ of a weak electrolyte is related to the dilution $(V)$ by the expression $\alpha = \sqrt{K_a \cdot V}$,where $K_a$ is the dissociation constant. As the dilution $(V)$ increases (which means the concentration decreases),the degree of dissociation $(\alpha)$ increases. Therefore,increasing the dilution leads to an increase in the degree of dissociation.
