* Sodium carbonate is a white crystalline solid which exists as a decahydrate, Na2CO3·10H2O. This is also called washing. soda. On heating, the decahydrate loses its water of crystallization to form monohydrate. Above 373K, the monohydrate becomes completely anhydrous and changes to a white powder called soda ash.
