When sodium carbonate is added into water and carbon dioxide gas is passed through the solution it gives sodium bicarbonate i.e baking soda
Na2CO3 + H2O +CO2 ---------> 2NaHCO3

By allowing the chemical reaction of carbon dioxide (CO2) + water (H2O) + ammonia (NH3) + sodium ion (Na+) ---> sodium hydrogen bicarbonate (NaHCO3) + ammonium cation (NH+4) are obtained.
Explanation:
- Further reaction of sodium hydrogen bicarbonate (NaHCO3) produces sodium bicarbonate (Na2CO3) + carbon dioxide (CO2) + water (H2O) using Solvay process.
- Sodium hydrogen bicarbonate (NaHCO3) is produced by recycling carbon dioxide produced from this reaction.
CO2 + H2O + NH3 + Na+ → NaHCO3 + NH+4
NaHCO3 → Na2CO3 + CO2 + H2O
