Nitric Acid

Nitric acid is a strong mineral acid with the chemical formula HNO3. It is a colorless liquid that is highly corrosive and can cause severe burns. Nitric acid is commonly used in the production of fertilizers, explosives, and in various industrial processes.

Properties of Nitric Acid

Below are some important properties of nitric acid:

Chemical Formula: HNO3
Molar Mass: 63.01 g/mol
Appearance: Colorless liquid
Odor: Pungent and suffocating
Solubility: Miscible with water
Corrosive: Can cause severe burns

Uses of Nitric Acid

Nitric acid has several important industrial and laboratory uses, including:

Production of fertilizers, such as ammonium nitrate
Manufacturing of explosives, like nitroglycerin and TNT
Etching and cleaning metals
Production of nylon
As a reagent in various chemical reactions

Chemical Reactions Involving Nitric Acid

Nitric acid can undergo various chemical reactions, including:

Dissociation: In water, nitric acid dissociates into hydronium ions (H3O+) and nitrate ions (NO3-).
Nitration: Nitric acid is used in the nitration of organic compounds, where it introduces a nitro group (-NO2) into the molecule.
Reduction: Nitric acid can be reduced to produce nitrogen dioxide (NO2) and other nitrogen oxides.

Safety Precautions

When handling nitric acid, it is important to observe proper safety precautions, including:

Wearing protective clothing, gloves, and goggles
Avoiding inhalation of fumes
Working in a well-ventilated area
Using nitric acid in a fume hood if possible
Having access to an eyewash station and safety shower
