NEETChemistryRedox Reactions
Why does nitric acid act as an oxidizing agent and react with PbO but not with PbO 2 ?
Options
- ANitric acid prefers to react with lower oxidation state compounds.
- BPbO has a higher electron affinity than PbO 2 .
- CPbO 2 is already in its highest oxidation state, making it unreactive with nitric acid.
- DNitric acid forms a protective layer on the surface of PbO 2 , preventing further reaction.
Correct answer
C. PbO 2 is already in its highest oxidation state, making it unreactive with nitric acid.
Step-by-step solution
Correct Option is : (C) PbO 2 is already in its highest oxidation state, making it unreactive with nitric acid.
