Faraday's laws of electrolysis

Faraday's work on the chemical reaction produced when an electric current passes through a liquid resulted in the laws of electrolysis.

The first law states that the amount of chemical change produced by a current is proportional to the quantity of electricity passed, ie equal currents produce equal amounts of decomposition.

The second law states that the quantities of substances liberated or deposited on the electrode by the passage of a given quantity of electricity (current) are proportional to the chemical equivalent weights of those substances.
