Solution

Baking Soda means Sodium Bicarbonate NaHCO3 when reacts with water H2O causes both exothermic and endo thermic reactions, gives Carbonic Acid which eventually release CO2.

NaHCO3 + H2O ----> H2CO3 + NaOH

H2CO3------> H2O + CO2

Exothermic is when H2CO3 (Carbonic Acid unstable) is formed and Endothermic is when CO2 is formed.
