Vedclass · Answer

(A) In the Solvay process for the production of sodium carbonate,ammonia is recovered by treating the ammonium chloride $(NH_4Cl)$ by-product with calcium hydroxide $(Ca(OH)_2)$.The chemical reaction is:$2NH_4Cl + Ca(OH)_2 \rightarrow 2NH_3 + 2H_2O + CaCl_2$From the reaction,it is clear that $CaCl_2$ (calcium chloride) is obtained as a by-product.

In the synthesis of sodium carbonate,the recovery of ammonia is done by treating $NH_4Cl$ with $Ca(OH)_2$. The by-product obtained in this process is
