Properties and Applications
Nitric acid (hydrogen nitrate) is a colorless liquid in its pure form, but it often appears yellowish due to decomposition into nitrogen oxides and water. It is miscible with water in all proportions and is a potent oxidizing agent.
Key Characteristics of HNO₃:
- Strong Acid: It fully dissociates in water, making it a strong electrolyte.
- Oxidizing Agent: Capable of oxidizing many metals and non-metals.
- Corrosive: Highly reactive with many substances, causing severe burns upon contact.
- Volatile: Has a high vapor pressure, producing pungent fumes.
Common Uses of Nitric Acid:
- Fertilizer Production: A primary component in manufacturing ammonium nitrate, a key agricultural fertilizer.
- Explosives: Used in the production of explosive compounds like nitroglycerin and trinitrotoluene (TNT).
- Metallurgy: Employed in the refining of precious metals, etching, and cleaning metal surfaces.
- Organic Synthesis: A crucial reagent in nitration reactions, introducing nitro groups into organic molecules.
- Laboratory Reagent: Widely used in chemistry laboratories for various analytical and synthetic procedures.
