Question

Following reaction describes the rusting of iron.
$4Fe+3O_2\to 4F{e}^{3+}+6O^{2-}$
Which one of the following statement is (are) correct?

• A. This is an example of a oxidation reaction
• B. Metallic iron is oxidised to $F{e}^{3+}$
• C. $F{e}^{3+}$ is an oxidizing agent
• D. Metallic iron is a strong reducing agent

Answer 1

Answer: (B), (D)

The correct options are
B Metallic iron is oxidised to $F{e}^{3+}$
D Metallic iron is a strong reducing agent

1. Option A is wrong as it is an example of redox reaction not just oxidation reaction. Iron is oxidised and oxygen is reduced in this reaction.
2. Option B is correct. Metallic iron is oxidised to ferric ion.
3. Option C is wrong. Oxygen is the oxidising agent here.
4. Option D is correct as iron is a strong reducing agent.

Hence, Option B and D are correct.
