Thermal Decomposition of Sodium Carbonate Decahydrate
Na2CO3·10H2O → Na2CO3 + 10H2O
نظرة عامة
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).
