sulfuric acid
Britannica Concise Encyclopedia | Date: 2007
[or oil of vitriol] Dense, colourless, oily, corrosive liquid inorganic compound (H2SO4). A very strong acid, it forms ions of hydrogen or hydronium (H+ or H3O+), hydrogen sulfate (HSO4), and sulfate (SO42). It is also an oxidizing ( oxidation-reduction) and dehydrating agent and chars many organic materials. It is one of the most important industrial chemicals, used in various concentrations in manufacturing fertilizers, pigments, dyes, drugs, explosives, detergents, and inorganic salts and acids, in petroleum refining and metallurgical processes, and as the acid in lead-acid storage batteries. It is made industrially by dissolving sulfur trioxide (SO3) in water, sometimes beyond the saturation point to make oleum (fuming sulfuric acid), used to make certain organic chemicals.
