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. ... When you add baking powder to water or milk, the alkali and the acidreact with one another and produce carbon dioxide – the bubbles.

Sodium bicarbonate is a weak base

 which is commonly known as baking soda and used in cooking. It weakly ionizes in water:

NaHCO3 + H2O → H2CO3 + (OH-) + (Na+).

In reaction with an acid, it liberates carbon dioxide gas:

NaHCO3 + (H+) →(Na+) +H2O + CO2.

This reaction is an important part of the leavening which takes place in baking. Baking powder contains sodium bicarbonate and a weak acid (cream of tartar

) in dry form. No reaction occurs in the dry powder, but when water is added for cooking, the reaction above occurs to release carbon dioxide to make the baked item "rise".
