Solution
The three oxyacids of nitrogen are:
(i) Nitric acid \[\ce{(HNO3)}\]
(ii) Nitrous acid \[\ce{(HNO2)}\]
(iii) Hyponitrous acid \[\ce{(H2N2O2)}\]
+3 oxidation state of nitrogen is observed in \[\ce{HNO2}\]. It undergoes disproportionation
\[\ce{\underset{+3}{3HNO2} -> \underset{+5}{HNO3} + \underset{+2}{2NO} + H2O}\]
+3 oxidation state changes to +5 and +2 oxidation states.
