Solution
Correct Answer:
Stronger oxidizing agent
- Standard Reduction Potential (E∘): A measure of the tendency of a chemical species to be reduced.
- Interpretation: A high positive E∘ means the species is very easy to reduce (Species+ne−→Product).
- Oxidizing Agent: Since the species 'wants' to take electrons from others to get reduced, it acts as a strong oxidizing agent.
- Example: Fluorine has the most positive E∘ and is the strongest oxidizing agent. Lithium has a very negative E∘, meaning its ion is hard to reduce, thus Li metal is a strong reducing agent.
This medium difficulty chemistry question is from the chapter electrochemistry, covering the topic of standard electrode potential. It appeared in the 2025 exam.
