Question

prepartion of sodium carbonate​

Answer 1

Answer:

Sodium carbonate is prepared by passing carbon dioxide through ammonia that gives ammonium carbonate. Subsequently ammonium carbonate is converted to ammonium hydrogen carbonate that reacts with sodium chloride to precipitate out sodium hydrogen carbonate. Sodium hydrogen carbonate later forms sodium carbonate.

2NH3 + H2O + CO2 (NH4)2CO3

(NH4)2CO3 + H2O + CO2 2NH4HCO3

2NH4HCO3 + NaCl NH4Cl + NaHCO3

2NaHCO3 Na2CO3 + CO2 + H2O

Answer 2

Sodium carbonate can be prepared by the heating of baking soda.

NaHCO3 ---Heat-----> Na2CO3 + H2O + CO2
