September 20, 2010 IKMAL’10 Page 2 Sulphuric Acid Uses of Sulphuric Acid Sulphuric acid is very important industrially, and has many uses including:a.
The production of fertilisers such as ammonium sulphate, potassium sulphate, calciumsuperphosphate (Ca(H SO 2 (g) or
Heating of metal sulphide such as lead(II) sulphide 2PbS(s) + 3O 2 (g) ---> 2PbO(s) + 2SO 2 (g)
or Combustion of hiydrogen sulphide 2H2S(g) + 3O 2 (g) ---> 2SO 2 (g) + 2H2O(ce)

September 20, 2010 IKMAL’10 Page 3The raw materials are sulphur and air (oxygen). Sulphur dioxide is produced by burning eithersulphur or ores which contain sulphur. Purification of sulphur dioxide 1.
The sulphur dioxide is then purified, by removing impurities like arsenic compounds whichwould otherwise poison the catalyst.2.
It is then passed through an electrostatic dust precipitator, which, as its name implies,charges dust particles which are then removed by being attracted to oppositely chargedplates. Stage 2 Formation of Sulphur trioxide sulphur dioxide + oxygen ---> sulphur trioxide 2SO 2 (g) + O
