Vedclass · Answer

(C) $HNO_2$ acts as both an oxidising and a reducing agent.It acts as a reducing agent when it reacts with strong oxidising agents like $KMnO_4$,$K_2Cr_2O_7$,and $H_2O_2$.It acts as an oxidising agent when it reacts with strong reducing agents like $HI$ and $H_2SO_3$.For example,it oxidises $Fe^{+2}$ to $Fe^{+3}$:$Fe^{+2} + HNO_2 + H^{+} \rightarrow Fe^{+3} + NO + H_2O$It reduces acidified $KMnO_4$:$2KMnO_4 + 3H_2SO_4 + 5HNO_2 \rightarrow K_2SO_4 + 2MnSO_4 + 3H_2O + 5HNO_3$
