$H_3PO_4, NO_2$

Vedclass · Answer

(A) Concentrated nitric acid acts as a strong oxidizing agent and oxidizes non-metals to their highest oxidation state. Phosphorus $(P_4)$ is oxidized to phosphoric acid $(H_3PO_4)$,where the oxidation state of phosphorus increases from $0$ to $+5$. Simultaneously,concentrated nitric acid $(HNO_3)$ is reduced to nitrogen dioxide $(NO_2)$,where the oxidation state of nitrogen decreases from $+5$ to $+4$. The balanced chemical equation is: $P_4 + 20 \ HNO_3 \rightarrow 4 \ H_3PO_4 + 20 \ NO_2 + 4 \ H_2O$

In the reaction of phosphorus with concentrated $HNO_3$,the oxidized and reduced products respectively are
