What happens when a solution of baking soda is heated? Write chemical equation for the same. Name the product which is reponsible for making the bread or cake spongy and fluffy.

Explanation

When baking soda is heated it decomposes to produce sodium carbonate, water and carbondioxide gas.
`2NaHCO_3 overset(Delta)to Na_2 CO_3 + H_2 O + CO_2`
`CO_2` gas produce during the reaction makes the cake or bread spongy and fluffy.
