Sulfuric acid, fuming with 30 percent or more free sulfur trioxide


Sulfuric acid (American spelling) or sulphuric acid (Commonwealth spelling), also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula H2SO4. It is a colorless, odorless and viscous liquid that is miscible with water.Pure sulfuric acid does not exist naturally due to its strong affinity to water vapor; for this reason, it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals since it is an oxidant with powerful dehydrating nature. Phosphorus pentoxide is a notable exception of not being affected by the acid's dehydrating property, which reversely dehydrates sulfuric acid to sulfur trioxide. Wikipedia
