Product Name:Potassium carbonate
English Name:Potassium carbonate
CAS No.:584-08-7
Aliases:Potash, Pearl ash, Crude potassium carbonate, Anhydrous potassium carbonate
Molecular Formula:K2CO3
Physical Properties:White powder or granules, readily soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. Hygroscopic, absorbs carbon dioxide and moisture from air and gradually converts to potassium bicarbonate. Melting point 891°C, boiling point 333.6°C, density 2.43 g/cm³.
