Mollie Nash · Accepted Answer

Step 1
The reduction potential of the given species are as follows:

M g^{2 +} (a q) + 2 e^{-} \Rightarrow M g (s)

E_{r e d}^{a} = - 2.38

Z n^{2 +} (a q) + 2 e^{-} \Rightarrow Z n (s)

E_{r e d}^{a} = - 0.76

C u^{+} (a q) + e^{-} \Rightarrow C u (s)

E_{r e d}^{a} = + 0.52

F_{2} (g) + 2 e^{-} \Rightarrow 2 F^{-} (a q)

E_{r e d}^{a} = + 2.87

The reduction potential of the given species is as given above.
Negative reduction potential denotes that the species has very less tendency to reduce, it has the tendency to gets oxidised.
Positive reduction potential denotes that the species has high tendency to get reduced and reduce the other specie present in the reaction.
Step 2
Positive reduction potential denotes that the species has high tendency to get reduced and reduce the other specie present in the reaction.

M g^{2 +} < Z n^{2 +} < C u^{+} < F_{2}

M g^{2 +}

and

Z n^{2 +}

have negative reduction potential. Thus, they behave as reducing agents and have least tendency to behave as oxidising agents. Between

M g^{2 +}

and

Z n^{2 +}, M g^{2 +}

has more negative potential potential than

Z n^{2 +}

, thus, it has least tendency to behave as oxidising agent.

C u^{+}

and

F_{2}

have positive reduction potential. Thus, they behave as strong oxidising agents. Between

C u^{+}

and

F_{2}, F_{2}

has more positive potential than

C u^{+}

, thus, it has highest tendency to behave as oxidising agent.
