Question

In the reaction $PbO+C\to 2Pb+C{O}_2$, the oxidizing agent is:

• A. $C$
• B. $PbO$
• C. $C{O}_2$
• D. $Pb$

Answer 1

Answer: (B)

$PbO$

$2PbO+C⟶2Pb+{CO}_2$

In the above reaction, oxidation state of $Pb$ decreases from $+2$ to $O$ and oxidation state of $C$ increases from $O$ to $+4$.

Therefore $PbO$ oxidises $C$ to ${CO}_2$. So $PbO$ is an oxidising agent.

$\therefore$ Correct answer is $B$.
