B. Amonia solvay process
Sodium carbonate (also known as soda ash) is produced by the Ammonia solvay process. The Ammonia solvay process is an industrial process used to produce sodium carbonate from salt (sodium chloride) and limestone. It involves the reaction of sodium chloride with calcium carbonate (from limestone) in a solution of ammonia to produce sodium carbonate and calcium chloride. The sodium carbonate is then recovered from the solution by crystallization.
A. The Haber process is used to produce ammonia.
C. The Decons process is not a well-known industrial process.
D. The Lead chamber process is used in the manufacture of sulfuric acid.
