Faraday's law of electrolysis
Faraday's law for electrolysis invented by Michael Faraday 1834:
- The mass of a substance produced at an electrode during electrolysis is proportional to the number of moles of electrons transferred at that electrode
- The number of Faradays required to discharge one mole of substance at an electrode is equal to the number of charges on that ion
- n = m/M = I·t / (z·F)
- n = amount of substance / mol
- m = mass / g
- M = molecular weight / (g/mol)
- z = number of "excess" electrons
- I = current / A
- t = time / s
- F = Faradayn constant (96500 C/mol)
