Give reasons:

1. Pure nitric acid fumes in moist air

2. Nitric acid on exposure evolves traces of oxygen even at ordinary temperatures

3.The brown fumes of nitric acid are stronger when copper is added to nitric acid and heated than heated alone.

1)=Nitric acid is a colorless liquid (depending upon purity and freshness). The acid produces fumes in moist air and has a strong choking odor. Long exposure to light causes nitric acid to beccme discolored (brownish). Commercial grades are approximately 70 - 71% pure.

2)= Being a powerful oxidizing agent, nitric acid reacts violently with many non-metallic compounds, and the reactions may be explosive. Depending on the acid concentration, temperature and the reducing agent involved, the end products can be variable.

3)=sorry I'm not sure if answer.
