How to make H2SO4????????

There are several methods to prepare sulphuric acid.

Process 1 : (i) Burning of sulphur to produce SO₂.

(ii) Sulphur dioxide is oxidised to sulphur trioxide in the presence of Vanadium oxide catalyst.

(iii) When it is dissolved in water it produces sulphuric acid.

                   SO₃ + H₂O ? H₂SO₄

Process 2 : Reacting Copper sulphate with Con.HCl produces Copper (II) Chloride and Sulphuric acid.

                    CuSO₄ + 2HCl ? CuCl₂ + H₂SO₄
