Sodium Carbonate (Washing Soda), Na2​CO3​⋅10H2​O Sodium carbonate

Sodium Carbonate (Washing Soda), Na2​CO3​⋅10H2​O Sodium carbonate is generally prepared by Solvay Process. In this process, advantage is taken of the low solubility of sodium hydrogencarbonate whereby it gets precipitated in the reaction of sodium chloride with ammonium hydrogencarbonate. The latter is prepared by passing CO2​ to a concentrated solution of sodium chloride saturated with ammonia, where ammonium carbonate followed by ammonium hydrogencarbonate are formed. The equations for the complete process may be written as : 2NH3​+H2​O+CO2​→(NH4​)2​CO3​(NH4​)2​CO3​+H2​O+CO2​→2NH4​HCO3​NH4​HCO3​+NaCl→NH4​Cl+NaHCO3​​ Sodium hydrogencarbonate crystal separates. These are heated to give sodium carbonate.
