How is sulphuric acid produced?

Answer 1

Sulphuric acid is produced by two major process industrially. 1. The contact and absorption process a.single contact single absorption process. b.double contact double absorption process. 2.The chamber process In the contact process, sulphur is burned in a furnace to produce sulphur dioxide which is then converted in to sulphur trioxide using catalyst converter. The catalyst is normally vanadium pentoxide. This sulphur trioxide gets absorbed in a absorption tower when it comes in contact with x% of sulphuric acid. x% contains some y% of water,this absorbs the sulphur trioxide to produce sulphuric acid. The equations are: Combustion process: S + O2 ---> SO2 (over V2O5) Conversion process: SO2 + 1/2 O2 ---> SO3 Absorption process: SO3 + H2O ---> H2SO4

Answer 2

Sulfuric acid is typically produced through the Contact Process, which involves burning sulfur to produce sulfur dioxide gas, converting the gas to sulfur trioxide in the presence of a catalyst, and then dissolving the sulfur trioxide in water to form sulfuric acid. This method is widely used on an industrial scale for the production of sulfuric acid.
