    Which of the following acid possesses oxidising, reducing and complex forming properties [MNR 1985]

    A) \[HN{{O}_{3}}\]

    B) \[{{H}_{2}}S{{O}_{4}}\]

    C) \[HCl\]

    D) \[HN{{O}_{2}}\]

    Correct Answer: D

    Solution :

      \[HN{{O}_{2}}\] can be either reduced to nitric oxide \[(NO)\] or oxidised to nitric acid and hence it acts both as an oxidising as well as a reducing agent. \[2HN{{O}_{2}}\,\to \,2NO+{{H}_{2}}O+[O]\] \[HN{{O}_{2}}+[O]\,\to \,HN{{O}_{3}}\]
