Sulphuric Acid
Sulfuric acid (H₂SO₄) at 98% concentration is one of the most widely used and important industrial chemicals globally. It is a highly corrosive, dense, oily liquid that is colorless to slightly yellow in appearance. Sulfuric acid is known for its strong acidic nature, powerful dehydrating properties, and ability to oxidize, making it a key reactant in a wide variety of chemical processes. In the solid state, sulfuric acid is a molecular solid that forms monoclinic crystals with nearly trigonal lattice parameters.
