Vedclass · Answer

(C) The Solvay process is used for the industrial production of sodium carbonate $(Na_2CO_3)$.The raw materials required are sodium chloride $(NaCl)$,ammonia $(NH_3)$,and limestone $(CaCO_3)$.The chemical reactions involved are:$2 NH_3 + H_2O + CO_2 \rightarrow (NH_4)_2CO_3$$(NH_4)_2CO_3 + H_2O + CO_2 \rightarrow 2 NH_4HCO_3$$NH_4HCO_3 + NaCl \rightarrow NaHCO_3 + NH_4Cl$$2 NaHCO_3 \xrightarrow{\Delta} Na_2CO_3 + H_2O + CO_2$Thus,the correct set of raw materials is $NaCl, NH_3, CaCO_3$.

Which among the following sets of compounds is used as raw material for the preparation of sodium carbonate by the Solvay process?
