Question

difference btween baking soda and washing soda by heating ​

Answer 1

They occupy different temperatures and expand differently.

Answer 2

Baking soda (NaHCO3) on heating produces carbon dioxide (CO2), which extinguishes a burning matchstick. But washing soda (Na2CO3.10H2O) on heating does not produce any such gas, thus, it has no effect on burning matchstick.
