Vedclass · Answer

(B) Pure nitric acid $(HNO_3)$ is a colorless liquid. When exposed to light,it undergoes photochemical decomposition to form nitrogen dioxide $(NO_2)$,water $(H_2O)$,and oxygen $(O_2)$.The chemical equation for this reaction is: $4HNO_3 \rightarrow 4NO_2 + 2H_2O + O_2$.The brown color is due to the presence of $NO_2$ gas.

Pure $HNO_3$ is colorless. However,it turns slightly brown when exposed to light due to its decomposition into $.....$.
