Vedclass · Answer

(B) Concentrated nitric acid $(HNO_3)$ is a colorless liquid when pure. However,it often appears yellow because of the decomposition of $HNO_3$ into nitrogen dioxide $(NO_2)$,water,and oxygen upon exposure to light or heat. The reaction is: $4HNO_3 \rightarrow 4NO_2 + 2H_2O + O_2$. The produced $NO_2$ gas dissolves in the concentrated $HNO_3$,imparting a yellow color to the liquid.

Concentrated $HNO_3$ is a yellow-colored liquid due to:
