The standard reduction potentials at 298 K for single electrodes are given below.

Electrode Electrode potential (volt)

Mg²⁺ /Mg -2.34

Zn²⁺ /Zn -0.76

Fe²⁺ /Fe -0.44

From this we can infer that

A. Zn can reduce both Mg²⁺ and Fe²⁺

B. Fe can reduce both Mg²⁺ and Zn²⁺

C. Mg can reduce both Zn²⁺ and Fe²⁺

D. Mg can reduce Zn²⁺ but not Fe²⁺
