    I'm Not John Bugess, but I think I know the answer.. Different
    metals will plate out of a solution at different voltages, this is a
    result of different oxidation potentials. The metal with the lowest
    E-zero value will plate out first is I recall corectly. And is also
    the reason why Iron will go into solution deducing copper out of
    solution giving that wonderful copper plating effect when one puts a
    silver piece into pickle with iron binding wire attached.
