Faradays Law  

Faradays Law deals with the relationship between chemical reactions, chemical change and electric energy. The following equality is important in all calculations using Faradays Law.

1 mole e- = 96500 coulombs = 1 ampere-second

An atom of Al tends to lose 3 moles of e-.   Al => Al+  + 3e-
An atom H tends to lose 1 mole of e-.          H => H+  + 1e-
An atom of Cu tends to lose 2 moles of e-.   Cu => Cu++  + 2e-
