`underset("Chloride")underset("Sodium")(NaCl) + underset("Ammonia")(NH_(3)) + H_(2)O + CO_(2) rarr underset("Hydrogen carbonate")underset("Sodium")(NaHCO_(3)) + underset("Chloride")underset("Ammonium")(NH_(4)Cl)`
uses of baking soda :
(i) It is used for making baking powder which is used for baking bread, cakes etc.
