Question

In the reaction, $4Fe+3O_2\to 4F{e}^{3+}+6O^{2-}$, which of the following statements is incorrect?

• A. It is a redox reaction
• B. Metallic iron is a reducing agent
• C. $F{e}^{3+}$ is an oxidising agent
• D. Metallic iron is reduced to $F{e}^{2+}$

Answer 1

The correct option is D Metallic iron is reduced to $F{e}^{2+}$

It is redox reaction because $Fe$ undergoes oxidation from 0 to +3 and $O$ undergoes reduction from 0 to -2.

As $Fe$ undergoes oxidation so it is reducing agent and ${Fe}^{+3}$ is reducing agent.

So only option D is incorrect because metallic iron is oxidized to +3.
