Solution
Baking soda is NaHCO3- Sodium hydrogen carbonate
Baking powder is NaHCO3+ Tartaric acid. If we add baking soda in making of cakes on heating it will produces sodium carbonate which will add bitter taste to the cake. To avoid this, tartaric acid is added to baking soda which produces sodium salt of acid and does not change the taste of cake.
e.g. 2NaHCO3heat−−→Na2CO3(bittertaste)+H2O+CO2
NaHCO3+H+(fromacid)heat−−→CO2+H2O+ sodium salt of acid
