How sodium carbonate is prepared
by solveys method? Throw light
on following 3 points
1) Principal
2) Diageom (labelled)
3) Chemical equation.​

Answer 1

Explanation:

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 + NacI ➡️ NH4CI + NaHCO3

2NaHCO3 ➡️ Na2CO3 + CO2 + H20
