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.
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
Safety Information:
