Name the process used for the industrial preparation of Sodium carbonate.
Answers
Answer:
The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na2CO3). The ammonia-soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. This method superseded the Leblanc process.
Answer:
The main industrial process for synthesizing sodium carbonate is the Solvay process, often known as the ammonia process.
Explanation:
In industrial preparation, the Solvay method is widely used to produce sodium carbonate (soda ash). The procedure retains Ernest Solvay's name because he invented it in the 1860s.
In the presence of dissolved ammonia, carbon dioxide reacts to produce ammonium carbonate and then ammonium hydrogen carbonate.
2NH₃ + H₂O + CO₂ → (NH₄)₂CO₃
(NH₄)₂CO₃ + H₂O + CO₂ → NH₄HCO₃
NH₄HCO₃ + NaCl + NH₄Cl → NaHCO₃
Crystals of sodium hydrogen carbonate separate. To create sodium carbonate, they are heated.
2NaHCO₃ (sodium bicarbonate) → Na₂CO₃ (sodium carbonate) + H₂O + CO₂
Hence, the name of the process used for the industrial preparation of sodium carbonate is the Solvay process.
The correct answer is the Solvay process.
