Faraday's Laws of Electrolysis

Michael Faraday's two laws of electrolysis put exact numbers on what electrolysis produces, turning it from a qualitative observation into a precise quantitative tool. The first law relates the mass produced at one electrode to the charge passed through that one cell; the second law compares the masses produced at different electrodes across DIFFERENT cells, when the identical charge is passed through all of them. Together, the two laws let the mass of any substance deposited or liberated during electrolysis be calculated directly from the current and the …
