Question

Which of the statements about the reaction below are incorrect for below equation? PbO + C Pb + CO a) Lead is getting reduced. b) Carbon dioxide is getting oxidised. c) Carbon is getting oxidized d) Lead oxide is getting reduced.​

Answer 1

Answer:

Both (a) and (b) is incorrect.

Explanation:

2PbO(s) + C(s) → 2Pb(s) + CO2(g)

Reduced substance – Pb

$Pb^{2+} + 2^{e–} → Pb$

Pb gains electrons or its oxidation number is reduced.

Oxidized substance – C

$C \rightarrow C^{2+}+2^{e-}\:$

C loses electrons or its oxidation number is increased.

Since oxygen is being removed and the removed oxygen from Lead is added to the elemental Carbon, lead is getting reduced and carbon dioxide is getting oxidized.

Hope this is helpful to you!
