Sulfuric acid history | ML2R consultancy

Sulphuric acid (American English: Sulfuric), H 2 SO 4, is a strong mineral acid.It can form any concentration in water. The old name for sulphuric acid is oil of vitriol. When high concentrations of SO 3 are added when making the acid, a solution of SO 3 in H 2 SO 4 results. This is called fuming sulphuric acid or Oleum or Nordhausen acid.
