Vedclass · Answer

(D) For a weak electrolyte,the degree of dissociation $(\alpha)$ increases with dilution according to Ostwald's dilution law. As dilution increases,the number of ions per unit volume increases due to the increase in the degree of dissociation,which leads to an increase in molar conductivity $(\Lambda_m)$. At infinite dilution,the electrolyte dissociates completely,but the concentration of ions becomes extremely low,making the conductivity $(\kappa)$ very small and difficult to measure accurately. Therefore,option $D$ is the correct statement.
