Q8
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
The standard reduction potentials at 298 K for single electrodes are given below.
From this we can infer that
| Electrode | Electrode potential (volt) |
| Mg2+ /Mg | -2.34 |
| Zn2+ /Zn | -0.76 |
| Fe2+ /Fe | -0.44 |
A.
Zn can reduce both Mg2+ and Fe2+
B.
Fe can reduce both Mg2+ and Zn2+
C.
Mg can reduce both Zn2+ and Fe2+
AnswerD.
Mg can reduce Zn2+ but not Fe2+
