For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.
<h3>What is the oxidizing agent?</h3>
In a redox reaction, the oxidizing agent is the one that gains electrons, causing the other element to oxidize.
Let's consider the following redox reaction.
Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq)
The corresponding half-reactions are:
Reduction: 2 e- + Cl₂(aq) ⇒ 2Cl⁻(aq)
Oxidation: 2 Br⁻(aq) ⇒ Br₂(aq) + 2 e-
Which best describes the oxidizing agent in this reaction?
- Bromine (Br) is the oxidizing agent because it gains an electron. NO. Br is the reducing agent.
- Bromine (Br) is the oxidizing agent because it loses an electron. NO. Br is the reducing agent.
- Chlorine (Cl) is the oxidizing agent because it gains an electron. YES.
- Chlorine (Cl) is the oxidizing agent because it loses an electron. NO. Cl gains electrons.
For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.
