Question

In the reaction: \[ \text{Zn} + \text{CuSO}_4 \rightarrow \text{ZnSO}_4 + \text{Cu} \] Which substance is oxidized?

• A. Zn
• B. CuSO\textsubscript{4}
• C. ZnSO\textsubscript{4}
• D. Cu

Hint:

LEO the lion says GER: \textbf{Loss of Electrons is Oxidation, Gain of Electrons is Reduction}.

Answer 1

The Correct Option is A

In a redox reaction, oxidation is the loss of electrons. In the given reaction: \[ \text{Zn} \rightarrow \text{Zn}^{2+} + 2e^- \quad \text{(Oxidation)} \] \[ \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \quad \text{(Reduction)} \] Zinc loses electrons and is thus oxidized. Copper ions gain electrons and are reduced.
