State and explain Faraday’s laws of electrolysis. What is the electrochemical equivalent?
First Law of Electrolysis: The mass deposited on any electrode is directly proportional to the quantity of electricity passing through it during electrolysis. W = zct Where, W = deposited mass on the electrode c = current and t = time in sec If 1 amp current is passed through a solution in one second then the deposited mass of substance on the electrode is equal to its electrochemical equivalent. Here, z is known as the electrochemical equivalent. Second Law of Electrolysis: The deposited masses on the electrodes is directly proportional to their chemical equivalents when the same quantity of electricity is passed through the different electrolytic cells. Consider, W1,W2&E1,E2W1,W2&E1,E2be the amount of mass deposited and their chemical equivalents respectively. According to faraday’s second law of electrolysis, W1αE1, and W2αE2 Then, W1/W2=E1/E2
