Question

discuss the various reactions that occur in the solvay process?

Answer 1

The solvay process or ammonia process is the major industrial process for the production of sodium carbonate. 1)The solvay process results in soda ash(predominantly sodium carbonate(Na2CO3)from brine(as a source of sodium chloride(NaCl)and from limestone(as a source of calcium carbonate(CaCO3).The overall process is; 2NaCl+CaCO3--------------->Na2CO3+CaCl2 2)In the first step in the process,carbon dioxide(CO2)passes through a concentrated aqueous solution of sodium chloride(table salt,NaCl) and ammonia (NH3) NaCl+CO2+NH3+H2O------------->NAHCO3+NH4CL(I)

Answer 2

☢ NH3 + CO2 + H2O + NaCl –––> NaHCO3 + NH4Cl

☢ NaHCO3 ––––>Na2CO3 + H2

☢ Na2CO3 + 10 H2O ––―――> Na2CO3.10H2O
