Faraday's laws of electrolysis

Faraday's law for electrolysis discovered 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

$n={\frac {m}{M}}={\frac {It}{zF}}$

$n=$ amount of substance (mols)

$m=$ mass (grams)

$M=$ molecular weight (grams per mol)

$z=$ number of "excess" electrons

$I=$ current (ampere)

$t=$ time (seconds)

$F=$ Faradayn constant (96500 C/mol)
