Thermal Decomposition of Sodium Carbonate Decahydrate

Na₂CO₃·10H₂O → Na₂CO₃ + 10H₂O

Visão geral

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).
