Statement: For a weak electrolyte, the plot of molar conductivity (Lambda_(m)) against sqrt(C )(C is concentration in mol litre^(-1)) is nearly linear. Explanation: The molar conductivity at infinite dilution (Lambda_(m)) for an electrolyte can be considered equal to the sum of the limiting molar conductivities of the individual ions.
