The chain of transformations.
1. The interaction of sodium with water with the formation of alkali.
2Na + 2H2O = 2NaOH + H2.
2. Passing carbon dioxide through an alkali solution.
2NaOH + CO2 = Na2CO3 + H2O.
Obtaining bicarbonate from sodium carbonate.
Na2CO3 + H2O + CO2 = 2NaHCO3.
3. Interaction of hydrocarbonate with sulfuric acid.
2NaHCO3 + H2SO4 = Na2SO4 + 3H2O + CO2.
4. Sodium sulfate with hydrochloric acid forms salt and sulfuric acid.
Na2SO4 + 2HCl = 2NaCl + H2SO4.
