Q. The standard reduction potentials at 298 K for single electrodes are given below.
Electrode electrode potential (volt)
$\text{Mg}^{\text{2+}} \text{/Mg}$ $- \text{2} \text{.34}$
$\text{Zn}^{\text{2+}} \text{/Zn}$ $- \text{0} \text{.76}$
$\text{Fe}^{\text{2+}} \text{/Fe}$ $- \text{0} \text{.44}$
From this we can tell that

Solution:

Metals with lower SRP can displace the metal with higher SRP from their solutions. Mg with lower $SRP (-2.34)$ can reduce both $Zn^{2 +} (-0.76) $ and $Fe^{2 +} (-0.44)$.
