1. Sulfur combustion in a stream of oxygen.
S + O2 = SO2.
2. Sulfur dioxide is oxidized to sulfuric gas.
2O2 + 2SO2 = 2SO3.
3. Formation of sulfuric acid.
SO3 + H2O = H2SO4.
4. Sulfuric acid forms sulfate with sodium hydroxide.
H2SO4 + 2NaOH = Na2SO4 + 2H2O.
5. The reaction of exchange of salts of barium and sodium.
Na2SO4 + BaCl2 = 2NaCl + BaSO4.
