Question

The following reaction describes the rusting of iron.
$4Fe+3O_2\to 4F{e}^{3+}+6O^{2-}$

Which one of the following statements is incorrect?

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

Answer 1

The correct option is B Metallic iron is reduced to $F{e}^{3+}$.

`The following reaction describes the rusting of iron.

$4Fe+3O_2\to 4F{e}^{3+}+6O^{2-}$

Here, metallic iron loses electrons to form $F{e}^{3+}$. Hence, it has been oxidised.

Therefore, statement is option B is incorrect.
