Answer:
The species oxidized: Pb
The species reduced: Fe³⁺
The oxidizing agent: Fe³⁺
The reducing agent: Pb
Explanation:
Let's consider the following redox reaction.
2 Fe³⁺ + Pb → 2 Fe²⁺ + Pb²⁺
We can write the corresponding half-reactions.
Oxidation: Pb → Pb²⁺ + 2 e⁻
Reduction: 2 Fe³⁺ + 2 e⁻ → 2 Fe²⁺
Pb is the species oxidized, and therefore it is the reducing agent.
Fe³⁺ is the species reduced, and therefore it is the oxidizing agent.
