SHORT DESCRIPTION

Nitric Acid 2.5 Litres Extra Pure is a high-purity, concentrated mineral acid supplied in a secure 2.5-litre packaging, ideal for laboratory and industrial applications requiring precision and consistency. Known for its strong oxidizing properties, nitric acid (HNO₃) is widely used in analytical chemistry, metal etching, sample digestion, and nitrate salt preparation.

This Extra Pure grade ensures minimal contaminants, making it especially suitable for trace analysis, high-purity synthesis, and quality control laboratories. Its sharp, acrid odor and highly corrosive nature demand careful handling with proper personal protective equipment (PPE), including acid-resistant gloves, goggles, and fume hoods. It must be stored in tightly sealed, compatible containers away from organic materials, bases, and flammable substances. This reagent is essential in both academic research and industrial processes involving nitration reactions, fertilizer formulation, and explosives development.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Wear acid-resistant lab coats, nitrile or neoprene gloves, and chemical splash goggles.
Use a face shield and work in a well-ventilated fume hood.
Use acid-resistant aprons and boots when handling large volumes.

Handling:

Handle with extreme care; nitric acid is highly corrosive and oxidizing.
Avoid contact with skin, eyes, and clothing.
Never mix with organic materials, reducing agents, or flammable substances.
Use only with proper ventilation and avoid inhalation of vapors.

Storage:

Store in a cool, dry, well-ventilated acid storage cabinet.
Keep the container tightly closed and upright.
Segregate from organic materials, bases, combustibles, and other incompatible chemicals.
Use only containers resistant to strong acids (e.g., glass or Teflon-lined materials).

FIRST AID MEASURES

Inhalation:

Move the person to fresh air immediately.
Provide oxygen if breathing is difficult.
Seek immediate medical attention.

Skin Contact:

Immediately flush skin with plenty of water for at least 15 minutes.
Remove contaminated clothing.
Seek medical attention even if no symptoms appear.

Eye Contact:

Rinse cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do.
Continue rinsing and seek immediate medical help.

Ingestion:

Do not induce vomiting.
Rinse mouth thoroughly with water (do not swallow rinse water).
Seek immediate medical assistance.

FIRE FIGHTING MEASURES

Flammability:

Nitric acid is not flammable, but it is a strong oxidizer and can intensify fires.

Extinguishing Media:

Use dry chemicals, carbon dioxide (CO₂), or water spray.
Do not use straight water streams on acid; it may cause splattering.

Hazardous Combustion Products:

Emits toxic and corrosive fumes including nitrogen oxides (NO, NO₂).

Firefighter Protection:

Wear self-contained breathing apparatus (SCBA) and acid-resistant full protective gear.
Cool containers with water spray from a safe distance.
