Question

Which of the given statement(s) is/are correct about the reaction mentioned below?

$2\text{PbO (s)}+\text{C (s)}\to 2\text{Pb (s)}+{\text{CO}}_2\text{(s)}$

• A. Lead is getting reduced.
• B. Carbon dioxide is getting oxidised.
• C. Carbon is getting oxidised.
• D. Lead oxide is getting reduced.

Answer 1

Answer: (C), (D)

The correct options are
C Carbon is getting oxidised.
D Lead oxide is getting reduced.

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

In the given reaction, carbon is gaining oxygen to form carbon dioxide whereas lead oxide is losing oxygen to form lead. This means carbon is getting oxidised and lead oxide is getting reduced.
