Question

Which among the following statements are correct for the given redox reaction?

$2{\text{Fe}}_2{\text{O}}_3\text{(s)}+3\text{C(s)}\to 4\text{Fe(s)}+3{\text{CO}}_2\text{(g)}$

• A. ${\text{Fe}}_2{\text{O}}_3$ is getting oxidised.
• B. ${\text{Fe}}_2{\text{O}}_3$ is getting reduced.
• C. $\text{C}$ is getting oxidised.
• D. $\text{C}$ is getting reduced.

Answer 1

Answer: (B), (C)

The correct options are
B ${\text{Fe}}_2{\text{O}}_3$ is getting reduced.
C $\text{C}$ is getting oxidised.

A substance is said to be oxidised if it either gains oxygen atom or loses hydrogen atom.

A substance is said to be reduced if it either loses oxygen atom or gains hydrogen atom.

In the given chemical reaction, ${\text{Fe}}_2{\text{O}}_3$ is reduced since it is losing an oxygen atom and $\text{C}$ is oxidized since it is gaining an oxygen atom.
