Chemical Properties

Sulfuric acid is a strong inorganic acid and the most important oxygen-containing acid of sulfur. It reacts vigorously with most metals and organic materials, exhibiting strong corrosive and oxidizing properties. Highly concentrated sulfuric acid is strongly hygroscopic and can act as a powerful dehydrating agent, carbonizing organic substances such as wood, paper, textiles, and biological tissues.

Mixing sulfuric acid with water generates significant heat; always add acid to water, never the reverse. Due to its corrosiveness and oxidizing nature, it must be handled with extreme caution.

Industrial Applications

Sulfuric acid is a key industrial chemical, often referred to as the "mother of chemical industry." Its uses include:

• Manufacture of chemical fertilizers
• Chemical synthesis
• Pharmaceuticals
• Plastics and detergents
• Explosives and pigments
• Batteries (lead-acid storage)
• Petroleum refining
• Metal smelting
• Dye and textile industry
• Used as a dehydrating and sulfonating agent in organic synthesis
• Laboratory reagent
