Thermal Decomposition of Sodium Carbonate Decahydrate

Na2CO3·10H2O → Na2CO3 + 10H2O

ภาพรวม

Washing soda (sodium carbonate decahydrate) loses its water of crystallization when heated. This dehydration reaction produces anhydrous sodium carbonate (soda ash). The hydrated crystals are transparent but become opaque white powder as water is driven off (efflorescence).
