i.   Laboratory method

       Baking soda can be prepared by saturating a cold solution of sodium carbonate with carbon dioxide.

  `Na_2CO_3  + CO_2   +H_2O \rightarrow 2NaHCO_3`

ii.   Industrial method

         Baking soda is prepared by passing carbon dioxide gas through brine (saturated solution of NaCl) saturated with ammonia.

  `NaCl + H_2O + CO_2 + NH_3 → NH_4Cl  + NaHCO_3`
