Zinc, Zn, is more easily oxidized than copper, Cu. What happens the moment after metal strips of these metals come into contact with each other? o The zinc metal begins to turn a greenish color indicating the presence of the formation of cupric oxide, Cuo. o The zinc metal immediately begins depositing electrons onto the surface of the copper, thus coating the copper with a white powder of zinc oxide, Zno. Nothing happens. An immediate build up of charge in either material prevents continued oxidation-reduction from occurring. o The surface of the copper appears moist and cloudy as the zinc metal oxidizes and gets dissolved into Zn(aq) ions.
