Why has the molar conductance of an electrolyte the maximum value at infinite dilution?

Answer»
  • As the dilution of an electrolytic solution increases or concentration decreases, the dissociation of an electrolyte increases.
  •  At infinite dilution, the dissociation of an electrolyte is complete (100% dissociation). Hence all the ions from one mole of an electrolyte are available to carry electricity.

Therefore the molar conductance at infinite dilute (∧0) for a given electrolyte has the highest or limiting value. It is always constant for the given electrolyte at constant temperature.
