    From a consideration of the data below determine which of the given species will oxidize Fe to Fe2+:
    Fe2+ + 2e- --> Fe; E° = -0.44 V
    Zn2+ + 2e- --> Zn; E° = -0.76 V
    Al3+ + 3e- --> Al: E° = -1.67 V
    Mg2+ + 2e- --> Mg; E° = -2.28 V
    Cu2+ + 2e- --> Cu; E° = +0.34 V

    a. Zn2+

    b. Al3+
