NaHCO 3 is mainly prepared by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water. Calcium carbonate is used as the source of CO 2 and the resultant calcium oxide is used to recover the ammonia from the ammonium chloride.The product shows a low purity (75%).aHCO 3 is mainly prepared by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water.
