*First Law
The quantity of a substance produced by electrolysis is proprotional to the quantity of electricty used.
*Second Law
For a given quantity of electricity the quantity of substance produced is proportional to its weight.
*The quantity of electricity or charge contained in a current running for a specified time can be calculated: Q = I x t
Q = quantity of electricity or charge in coulombs (C)
I = current in amps (A)
t = time (seconds)
*The Faraday constant, F, is the quantity of electricity carried by one mole of electrons.
F = Avogadro's Number x charge on electron in coulombs
F = 6.022 x 1023 mol-1 x 1.602192 x 10-19 C
F = 96,484 C mol-1
This is usually rounded off to 96,500 C mol-1 for calculations in chemistry.
