Sulfuric(VI) acid is a highly corrosive strong mineral acid composed of sulfur, oxygen, and hydrogen. It is one of the most important industrial chemicals, used in a wide range of applications, from chemical manufacturing to materials processing and environmental engineering. The concentrated form (96–98%) is particularly reactive and hygroscopic.

Chemical and Physical Properties
Density: 1.84 g/cm³ (at 20°C)
Melting Point: 10°C
Boiling Point: 337°C (decomposes partially)
Solubility in Water: Completely miscible with water (exothermic reaction)
Solubility in Other Solvents: Miscible with ethanol and methanol; reacts with many organic solvents
Odor: Odorless (may release choking fumes when decomposing)

Applications
Chemical Manufacturing: Used in the production of fertilizers, explosives, dyes, and detergents.
Petroleum Industry: Employed in refinery processes such as alkylation.
Batteries: Serves as the electrolyte in lead-acid batteries.
Surface Treatment: Used for metal pickling, cleaning, and electroplating preparation.
Laboratory Use: Acts as a strong acid catalyst, dehydrating agent, and analytical reagent.

Safety

Signal Word: Danger

Handling and Storage
Storage Conditions: Store in a tightly closed, corrosion-resistant container in a cool, dry, and well-ventilated area. Protect from moisture and incompatible materials such as organic substances, bases, and reducing agents.
Handling Precautions: Add acid to water, never the reverse. Use full PPE and conduct work in a fume hood or well-ventilated area.

Attention!
Sales Restrictions: Sales and transport of concentrated sulfuric acid are regulated in many countries due to its potential for misuse. Authorization, licensing, or end-user declarations may be required.
