Electrolytic Concuctance

The passage of a current through an electrolyte involves the movement of ions carrying an electric charge and so the study of electrolytic conduction may supply useful chemical information.The magnitude of the conductance, i.e., the reciprocal of resistance, depends mainly on three factors: the number of ions, magnitude of charge on each ion and the ionic mobility.The conductance of an electrolyte may be measured in terms of molar conductance, that is, the conductance due to one mole of an ionic solute and secondly, the equivalent conductance, that is, the conducting power of all ions produced by one equivalent of the electrolyte in the given solution. But to compare the conductance of two solutions, equivalent conductance is considered because one equivalent of different electrolytes involves the same number of electrons in accordance with Faraday's second law of electrolysis while one mole of different electrolytes may or may not involve the same number of electrons. In other words, the solutions, each containing one equivalent of different electrolytes, are equivalent in terms of moles of electrons being carried.
