Question

balanced equation for preparation of sodium carbonate from sodium hydrogen carbonate

Answer 1

Chemical formula – NaHCO3

            Chemical name – sodium hydrogen carbonate

            Common name – baking soda

            In the preparation of baking soda, a solution of sodium chloride in water is saturated                   with ammonia and then CO2 is passed into the liquid,

Nacl + H2O + CO2 + NH3 – NH4Cl + NaHCO3

            Baking soda is a mild non corrosive The following reaction takes place when it is heated             during cooking

            2HaHCO3 D Na2CO3. + H2O + CO2


Chemical name – sodium carbonate

Chemical formula – Na2CO3, 10H2O

            Common name – washing soda

            Washing soda can be obtained by recrystallisation of sodium carbonate of sodium                       carbonate sodium carbonate can be obtained by heating baking soda

Na2co3 + 10H2O – Na2CO3. 10H2O
