Nitric acid (CAS NO.7697-37-2) is a colorless, highly corrosive liquid and a very powerful oxidizing agent that in the highly pure state is not entirely stable and must be prepared from its azeotrope by distillation with concentrated sulfuric acid. Nitric acid gradually yellows because of decomposition to nitrogen dioxide. Solutions containing more than 80% nitric acid are called fuming nitric acids. Something you should know ahout it as As follows:
1. Fire Fighting Measures of Nitric acid
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with other material may cause fire. Substance is noncombustible.
Extinguishing Media: Do NOT use water directly on fire. Use water spray to cool fire-exposed containers. Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.
2. Handling and Storage of nitric acid
Handling: Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood.
Storage: Do not store near combustible materials. Store in a cool, dry place. Store in a tightly closed container. Corrosives area.
