Vedclass · Answer

(A) In the Solvay process,the overall reaction is: $2NaCl + CaCO_3 \rightarrow Na_2CO_3 + CaCl_2$. The process involves the use of $NH_3$ as a catalyst,which is recovered by reacting the byproduct $NH_4Cl$ with $Ca(OH)_2$: $2NH_4Cl + Ca(OH)_2 \rightarrow 2NH_3 + CaCl_2 + 2H_2O$. Additionally,$CO_2$ is recovered from the thermal decomposition of limestone: $CaCO_3 \rightarrow CaO + CO_2$. Thus,$NH_3$ and $CO_2$ are the products that are recycled back into the process.

Sodium carbonate is manufactured by the Solvay process. The products that are recycled are:
