1. Combustion of sulfur in oxygen with the release of sulfur dioxide. Addition reaction.
S + O2 = SO2.
2. Oxidation to trioxide. Addition reaction.
2SO2 + O2 = 2SO3.
3. Formation of sulfuric acid in reaction with water of sulfuric anhydride. Addition reaction.
SO3 + H2O = H2SO4.
4. Obtaining potassium sulfate and hydrochloric acid by the interaction of sulfuric acid and potassium chloride. Exchange reaction.
H2SO4 + 2KCl = K2SO4 + 2HCl.
5. The reaction of exchange of potassium sulfate with a salt of barium with the formation of the corresponding salts – potassium chloride and barium sulfate.
K2SO4 + BaCl2 = 2KCl + BaSO4.
