answered-by-expert Expert Answer

General methods of preparation of sulphuric acid are as follows:

  • By the action of heat on nitric acid and sulphur.

                S + 6HNO3 → 6NO2 + 2H2O + H2SO4

  • By passing chlorine through an aqueous solution of sulphur trioxide.

                Cl2 + SO2 + 2H2O →2HCl + H2SO4

  • By dissolution of sulphur trioxide in water.

                 SO3 + H2O →H2SO4

  • By hydrolysis of sulphuryl chloride.

                SO2Cl2 + 2H2O →H2SO4 + 2HCl
