Single Displacement Reaction: Zinc and Copper(II) Ion ...

Oxidation-reduction reactions involve the transfer of electrons between substances. In this reaction, zinc atoms each will lose two electrons (oxidation) and become Zn 2 + ions. The two electrons that are released by zinc will be gained by the Cu 2 + ions (reduction). The Cu 2 + ions become Cu atoms.. Total equation: Zn (s) + CuSO 4 (aq) --> Cu (s) + ZnSO 4 (aq)
