Question

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

• A. This is an example of redox reaction
• B. Metallic iron is reduced to $F{e}^{3+}$
• C. Metallic iron is reducing agent
• D. $O_2$ is an oxidising agent

Answer 1

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

$4\stackrel{0}{Fe}+3\stackrel{0}{O_2}\to 4F{e}^{3+}+6O^{2-}$
This is a redox reaction.
Here, $Fe$ is oxidised to $F{e}^{3+}$. So, it is a reducing agent.
Oxygen is reduced to $O^{2-}$ and is an oxidising agent.
