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.

What is Solvay process with example?

: a process for making soda from common salt by passing carbon dioxide into ammoniacal brine resulting in precipitation of sodium bicarbonate which is then calcined to carbonate.

Which salt is obtained by Solvay process?

a process for manufacturing sodium carbonate whereby a concentrated solution of sodium chloride is saturated with ammonia, carbon dioxide is passed through it, and the product is calcined.
