Solution
The correct option is ANaCl+CaCO3⟶Na2CO3+CaCl2 The following reactions occur during the Solvay's process for the manufacture of Na2CO3. (A) NH3+H2O+CO2⟶NH4HCO3 (B) 2NaHCO3Δ−→Na2CO3+CO2+H2O (D) 2NH4Cl+Ca(OH)2⟶2NH3+CaCl2+2H2O The following reaction does not occur during the Solvay's process for the manufacture of Na2CO3. (C) NaCl+CaCO3⟶Na2CO3+CaCl2 Ammonia soda process (Solvay's process) is the process for the preparation of sodium carbonate. The raw materials used are NaCl,NH3 and CO2.
