Statement 5.

#### Explanation:

$\text{Mg} \left(s\right)$ is the reducing agent, donating $2$ electrons to the ${\text{Cu}}^{2 +}$ ion, thereby losing $2$ electrons $\to$ ${\text{Mg}}^{2 +}$ (oxidized).

${\text{Cu}}^{2 +}$ is the oxidizing agent, stealing $2$ electrons from the $\text{Mg} \left(s\right)$, thereby becoming reduced in the process.

Reducing agents (a.k.a. reductants) become oxidized in the process of reducing a species. Oxidizing agents (oxidants) become reduced by convention.

Also, these agents are found on the reactants' side.
