Sulfuric acid is a highly corrosive strong mineral acid with the molecular formula H 2 SO 4. It is a pungent colourless to slightly yellow viscous liquid which is soluble in water at all concentrations. Sometimes it is dyed dark brown during production to alert people to its hazards. The historical name of this acid is oil of vitriol.
