The chemical effects of electric current is used in industries or factories for the following purposes: 1) Electroplating metals. 2)Purification of metals. 3)Production of certain metals from the ore. … The electrolyte should contain positive ions (cations) of the metal to be deposited. These cations are reduced at the cathode to the metal in the zero valence state. For example, the electrolyte for copper plating can be a solution of copper(II) sulphate, which dissociates into Cu cations and SO 4 anions. At the cathode, the Cu is reduced to metallic copper by gaining two electrons.
