The Chemistry of Copper Electrolysis - Superfund
superfund.arizona.eduobvious). A dilute aqueous solution of copper sulfate and sulfuric acid is used as the electrolyte. An electric current is provided by a 9 volt (V) battery. When electric current is supplied to the anode (penny) via the positive terminal of the battery, copper atoms are oxidized to form cations with a positive charge (Cu2+). The cations are set ...
