Description
An oily, fuming, corrosive liquid. Sulfuric acid was the highest volume chemical produced in the USA in 1991. Valentine, a 15th century German alchemist , is credited with its discovery (Schur 1985). Called oil of vitriol, it was prepared by the distillation green vitriol (Ferrous sulfate) and blue vitriol (Copper sulfate). Sulfuric acid is very reactive, dissolving most metals and sulfonating most organic compounds. It is used in etching and cleaning solutions for printing and photography. Sulfuric acid is also used in leather manufacture for bleaching, deliming, and pickling. Oleum or Nordhausen acid are common names used for fuming sulfuric acid (93-96%). Brown oil of vitriol (B.O.V.) is an old name for concentrated sulfuric acid (about 70%).
Synonyms and Related Terms
hydrogen sulfate; battery acid; electrolyte acid; sulphuric acid (Br.), oil of vitriol; BOV; brown oil of vitriol; oleum; Nordhausen acid
