Sodium Carbonate High Quality Anhydrous Soda Ash Na2CO3 CAS 497-19-8
Sodium carbonate is a white odorless powder or particle at room temperature. It has water absorption property and gradually absorbs 1mol / L water in the exposed air (about = 15%). Soluble in water and glycerin. It is slightly soluble in anhydrous ethanol and difficult to dissolve in propanol. The solution is alkaline and can make phenolphthalein red.
