Thermal Decomposition of Sodium Carbonate Decahydrate

Na2CO3·10H2O → Na2CO3 + 10H2O

अवलोकन

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).

रोजमर्रा का उदाहरण

When washing soda crystals are left in dry air, they slowly lose water and turn into a white powder through this efflorescence process.

औद्योगिक महत्व

Anhydrous sodium carbonate (soda ash) is a major industrial chemical used in glass manufacturing, detergents, water treatment, and as a chemical feedstock.
