Dear student,


  • 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 =Na 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
