Answer:
In Solvay process, also known as ammonia soda process, carbon dioxide is passed through a brine solution (containing about 28 % NaCl) which is saturated with ammonia to form sodium carbonate.
2NH 3 +H 2O+CO 2 →(NH 4 ) 2 CO 3(NH 4)2+CO 3 +H2O+CO 2 →2NH 4 HCO 3 NH 4 HCO3 +NaCl→NaHCO 3 ↓+NH 4 Cl
The precipitate of sodium bicarbonate is filtered, dried and ignited to form sodium carbonate.
2NaHCO 3heat Na 2 CO 3 +CO 2 +H 2 O
The carbon dioxide required for the reaction can be obtained by heating limestone (calcium carbonate) to 1300 K in a lime klin. Lime dissolves in water to form calcium hydroxide which is then transferred to the ammonia recovery tower.
CaCO 3heat CaO+CO2 CaO+H 2 O→Ca(OH) 2
Ammonia required for the process can be prepared by heating ammonium chloride with calcium hydroxide. 2NH 4 Cl+Ca(OH) 2 2NH3 +CaCl 2 +H 2 O
Hence, the only byproduct of the reaction is calcium chloride.
