Na₂CO₃ is manufactured by solvay process, the products that are recycled are
Options
(a) CO₂ and NH₄Cl
(b) CO₂ and NH₃
(c) NaCl and CaO
(d) CaCl₂and CaO
Correct Answer:
CO₂ and NH₃
Explanation:
In the Solvay process for the manufacture of Na₂CO₃, following reactions occur in ammonia recovery tower.NH₄HCO₃ → NH₃ + CO₂ + H₂O, 2NH₄Cl + Ca(OH)₂ → CaCl₂ + 2NH₃ + 2H₂O. Now the ammonia along with a small amount of carbon dioxide is pumped to the top of the brine saturation tower.
