Faraday's laws of electrolysis predicts the amount of substance altered at the electrode due to the electricity that is transferred at the electrode. The term "z" or "electrochemical equivalent" corresponds to the ratio of the molar mass of that substance with the valency number of the ions of that substance (i.e, z= Molar mass/valency).
