In the following question, a statement of assertion is followed by a statement of reason. Mark the correct choice.
Assertion : HNO3 acts only as oxidising agent while HNO2 can act both as a reducing agent and an oxidising agent.
Reason : In HNO3, oxidation state of nitrogen is +5 which is maximum. In HNO2, oxidation state of nitrogen is +3 which can change from –3 to +5.
Assertion : HNO3 acts only as oxidising agent while HNO2 can act both as a reducing agent and an oxidising agent.
Reason : In HNO3, oxidation state of nitrogen is +5 which is maximum. In HNO2, oxidation state of nitrogen is +3 which can change from –3 to +5.
