1. Cathode: $\text{Mg}^{2+} + 2e^- \rightarrow \text{Mg}$; Anode: $2\text{Cl}^- \rightarrow \text{Cl}_2 + 2e^-$
2. Cathode: $2\text{Cl}^- + 2e^- \rightarrow 2\text{Cl}$; Anode: $\text{Mg}^{2+} \rightarrow \text{Mg} + 2e^-$
3. Cathode: $\text{Mg} \rightarrow \text{Mg}^{2+} + 2e^-$; Anode: $2\text{Cl}^- + 2e^- \rightarrow \text{Cl}_2$
4. Cathode: $\text{Mg}^{2+} + 2e^- \rightarrow \text{Mg}$; Anode: $\text{Cl}_2 + 2e^- \rightarrow 2\text{Cl}^-$
