Faraday Laws of Electrolysis is: (1) First Law: W = zit. Where W = weight of ions liberated from an electrolyte, z = electrochemical equivalent (E.C.E.), t = time in seconds from which current is passed, i = current in amperes. (2) Second Law: It states, If the same quantity of electricity passes through various electrolytes, the among of ions liberated at different electrodes are proportional to their chemical equivalents (E).
