Description
White, odorless crystals. Sodium carbonate has three distinct hydrated forms. The monohydrate is commonly called sodium carbonate while anhydrous sodium carbonate is called Soda ash, and sodium carbonate decahydrate is called Sal soda, or natron. Anhydrous sodium carbonate occurs in nature as the mineral thermonatrite. It forms a strongly alkaline aqueous solution and is used in the manufacture of Leather and Paper. Sodium carbonate is used as an ingredient in some types of Glass, detergents, bleaches, and water softeners. It is also used in photographic developing baths and textiles Dye baths.
Synonyms and Related Terms
soda; sodium carbonate monohydrate; soda monohydrate; soda crystals; calcined soda ash
