Electrolysis
In eletrolysis electrical energy is transformed into chemical energy.
When an electric charge is passed through chemicals having ions mostly in solution or molten state it results into addition reduction which consequently deposit or liberate chemical ions at electrdes.
One mole of e- holds a charge of approximately 96500 coloumbs which is shortly called as 1 Faraday charge.
When 1 Faraday charge is applied to a chemical substance it result into change of 1 equivalent of that specific chemical substance.
1 Faraday charge unit is very large for experimental purpose, thus sometimes chemist study by 1 coloumb of charge this is then known as to create an effect on 1 electro chemical equivalent.
Redox Cathode (Reduction) Auode (acidic)
Na+ + e- → Na Cl → e-
Na+ + e- → Na
Na+ + e- → Na Cl + Cl → Cl2
