  • question_answer
    In which of the following reactions \[HN{{O}_{3}}\]will not act as an oxidising agent?

    A) \[HN{{O}_{3}}+{{H}_{2}}S{{O}_{4}}\to \]

    B) \[HN{{O}_{3}}+FeS{{O}_{4}}+{{H}_{2}}S{{O}_{4}}\to \]

    C) \[KI+HN{{O}_{3}}\to \]

    D) none of the above

    Correct Answer: A

    Solution :

    \[HN{{O}_{3}}+{{H}_{2}}S{{O}_{4}}\to NO_{2}^{+}+HSO_{4}^{-}+{{H}_{2}}O\] In this reaction \[HN{{O}_{3}}\] is acting as \[O{{H}^{-}}\]donor and \[{{H}_{2}}S{{O}_{4}}\] as \[{{H}^{+}}\] donor. This is not a redox reaction.
