Vedclass · Answer

(C) $NO_2$ is a mixed anhydride of nitrous acid $(HNO_2)$ and nitric acid $(HNO_3)$.When $NO_2$ reacts with $H_2O$,it undergoes disproportionation:$2NO_2 + H_2O \rightarrow HNO_2 + HNO_3$When this mixture reacts with $NaOH$,it forms the corresponding sodium salts:$HNO_2 + HNO_3 + 2NaOH \rightarrow NaNO_2 + NaNO_3 + 2H_2O$Thus,it forms a mixture of nitrate and nitrite salts.

$NO_2$ is a mixed oxide. This is proved by the fact that it reacts with $H_2O$ and then with $NaOH$ to form:
