                     STUDY OF SALTS-

                              3.  Baking Soda  (Common Name)
               OR
                               Chemical Name –Sodium Hydrogen Carbonate

                               Chemical Formula – NaHCO
                                                                3





















                               Preparation of Baking Soda-
                     Baking Soda is prepared by Solvay’s Process-

                In this process–
                         i.   carbon dioxide,
                        ii.   water,
                        iii.   ammonia and
                        iv.   brine solution in its concentrated form,
                are used as raw materials.

                     The important chemical reaction that takes place is:

               CO +H O +NH +NaCl   → NaHCO +NH Cl
