Introduction: Both of them electrolytic cells and galvanic cells give wonderful samples of conversion of one form of energy into another. In an electrolytic cell, a present is passed through a fluid medium (solutions, molten salts) causing migration of ions towards electrodes as well as the charge deposition by the ions at the electrodes. For example, if a current is passed through a solution of sodium chloride, the following reactions occur at the cathode and anode.
