State the basic principle involved in Solvay process ...
Basic Principle involved in Solvay Process- It is based on low solubility of sodium hydrogen carbonate (NaHCO 3) whereby it gets precipitated in the reaction of sodium chloride with NH 4 HCO 3.The latter is prepared by passing CO 2 to a concentrated solution of NaCl saturated with ammonia, where ammonium carbonate followed by NH 4 HCO 3 are formed. The equations are …

The Solvay soda ash process is the classic example of the replacement of an infeasible reaction by a cluster of feasible chemical reactions involving the closed-cycle use of intermediate chemicals. Many industrial processes are based on this strategy. Previously, there had been no principles to guide the development of the proper sequence.
