Vedclass · Answer

(A) The reaction of concentrated nitric acid $(HNO_3)$ with $P_4O_{10}$ leads to the dehydration of the acid to form dinitrogen pentoxide $(N_2O_5)$: $4HNO_3 + P_4O_{10} \rightarrow 2N_2O_5 + 4HPO_3$. The reaction of concentrated nitric acid with phosphorus $(P_4)$ leads to the oxidation of phosphorus to phosphoric acid $(H_3PO_4)$ and the reduction of nitric acid to nitrogen dioxide $(NO_2)$: $P_4 + 20HNO_3 \rightarrow 4H_3PO_4 + 20NO_2 + 4H_2O$. Thus,the oxides obtained are $N_2O_5$ and $NO_2$ respectively.

The oxides of nitrogen obtained by the reaction of nitric acid with $(i)$ $P_4O_{10}$ and $(ii)$ $P_4$ respectively are:
