Solution

Identification of the Ion Oxidized

  1. Understand the Half Equations:

    • The cathode reaction is:
      Na++eNa \text{Na}^+ + e^- \rightarrow \text{Na}
    • The anode reaction is:
      2ClCl2+2e 2\text{Cl}^- \rightarrow \text{Cl}_2 + 2e^-
  2. Define Oxidation:

    • Oxidation is the process where an ion or atom loses electrons.
  3. Analyze Anode Reaction:

    • In the anode half reaction, Cl \text{Cl}^- ions lose electrons to form Cl2 \text{Cl}_2 .
  4. Conclusion:

    • Since Cl \text{Cl}^- is losing electrons during this process, it is the ion that is oxidized.

Final Answer

The ion that is oxidized in the given half equations is Cl \text{Cl}^- .
