Sulfuric acid 98-95% is a dense, oily, and highly corrosive strong mineral acid widely used in industrial and laboratory applications.
🏭⚗️ Production
It is primarily produced by the Contact process, which involves the catalytic oxidation of sulfur dioxide to sulfur trioxide, followed by absorption in water to form concentrated sulfuric acid.
🔬 Properties
The chemical formula is H₂SO₄ with a molar mass of approximately 98.08 g/mol. It appears as a colorless to slightly yellow viscous liquid, highly soluble in water with a strong exothermic reaction. It has a high boiling point (~337 °C) and is a strong dehydrating and oxidizing agent.
🧪 Applications
Sulfuric acid is widely used in fertilizer production (especially phosphates), petroleum refining, chemical synthesis, metal processing, battery acid, and wastewater treatment. It also serves as a key reagent in laboratories for pH adjustment and digestion.
⚠️ Safety
Highly corrosive and toxic, it can cause severe burns to skin and eyes and respiratory tract damage if inhaled. Handling requires full protective equipment including acid-resistant gloves, goggles, and face shield. It should be stored in corrosion-resistant containers, away from water and incompatible materials.
