Nitric acid is a strong oxidising acid used wherever metals must be cleaned, pickled, or nitrated. Because it is both corrosive and a powerful oxidiser, it demands more careful storage and handling than a simple mineral acid.

Supreme Petro Chemicals supplies nitric acid from Chennai to metal-processing, chemical, and laboratory buyers across South India.

What Is Nitric Acid?

Nitric acid has CAS number 7697-37-2 and molecular formula HNO3. Commercial concentrations are typically around 60–70%; fuming grades are higher and more aggressively oxidising. Always specify concentration, because handling and material compatibility change sharply with strength.

Industrial Applications

Metal pickling: Cleaning and surface preparation of stainless steel and other metals before finishing.
Nitration chemistry: Production of nitro compounds and intermediates.
Surface treatment: Passivation of stainless steel.
Laboratories: Reagent and digestion acid where the correct grade is specified.
Fertiliser and chemical manufacturing: Feedstock in selected processes.

Oxidiser Handling and Storage

Nitric acid is corrosive and a strong oxidiser. Keep it away from organics, reducing agents, and incompatible metals, and store it in compatible containers in a cool, ventilated area. Use acid-resistant PPE, face protection, and compatible transfer equipment, and follow the SDS for spill response and incompatibilities.

Packaging and Supply

Nitric acid is commonly supplied in carboys and drums depending on concentration and site controls. Specify concentration, quantity, packing, and delivery location, and confirm your receiving site has compatible storage and spill containment.
