Vedclass · Answer

(D) The Solvay process involves the following main steps:$1$. Formation of ammonium bicarbonate: $NH_3 + H_2O + CO_2 \rightarrow NH_4HCO_3$ (No redox change).$2$. Formation of sodium bicarbonate: $NH_4HCO_3 + NaCl \rightarrow NaHCO_3 + NH_4Cl$ (No redox change).$3$. Calcination of limestone: $CaCO_3 \rightarrow CaO + CO_2$ (No redox change).$4$. Recovery of ammonia: $2NH_4Cl + Ca(OH)_2 \rightarrow 2NH_3 + CaCl_2 + 2H_2O$ (No redox change).Since none of the steps in the Solvay process involve a change in oxidation states of the elements,the correct answer is none of these.

In chloro-alkali industries,during the Solvay ammonia process,a redox change occurs during:
