What is Faraday's Law of Electrolysis?
Faraday's Laws of Electrolysis describe the relationship between the amount of substance deposited or dissolved at an electrode and the quantity of electric charge passed. The first law states that the mass of substance deposited is proportional to the quantity of electricity. The second law states that for the same quantity of electricity, the masses of different substances deposited are proportional to their equivalent weights.
