Faraday's laws of electrolysis. One mole of electric charge (96,500 coulombs), when passed through a cell, will discharge half a mole of a divalent metal ion such as Cu 2 +.This relation was first formulated by Faraday in 1832 in the form of two laws of electrolysis:. The weights of substances formed at an electrode during electrolysis …
