The correct Answer is:
To determine the strongest oxidizing and reducing agents from the given standard reduction potentials, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Oxidizing and Reducing Agents**: - An oxidizing agent is a substance that gains electrons (is reduced) and has a high standard reduction potential. - A reducing agent is a substance that loses electrons (is oxidized) and has a low standard reduction potential. 2. **List the Given Half-Reactions with Their Standard Reduction Potentials**: - \( F_2(g) + 2e^- \rightarrow 2F^-(aq.), \quad E^\circ = +2.87 \, V \) - \( Cl_2(g) + 2e^- \rightarrow 2Cl^-(aq.), \quad E^\circ = +1.36 \, V \) - \( Br_2(g) + 2e^- \rightarrow 2Br^-(aq.), \quad E^\circ = +1.09 \, V \) - \( I_2(s) + 2e^- \rightarrow 2I^-(aq.), \quad E^\circ = +0.54 \, V \) 3. **Identify the Strongest Oxidizing Agent**: - The strongest oxidizing agent will have the highest standard reduction potential. - Among the given values, \( +2.87 \, V \) (for \( F_2 \)) is the highest. - Therefore, the strongest oxidizing agent is \( F_2 \). 4. **Identify the Strongest Reducing Agent**: - The strongest reducing agent will have the lowest standard reduction potential. - Among the given values, \( +0.54 \, V \) (for \( I_2 \)) is the lowest. - Therefore, the strongest reducing agent is \( I^- \). 5. **Conclusion**: - The strongest oxidizing agent is \( F_2 \) and the strongest reducing agent is \( I^- \). ### Final Answer: - The strongest oxidizing and reducing agents respectively are: **\( F_2 \) and \( I^- \)**.
