Sodium Carbonate Soda Ash Na2CO3 Food Grade 99.2% Min Soda Ash Light
Sodium carbonate, also called soda ash, is an inorganic compound with a molecular formula of Na2CO3. It is an important inorganic chemical raw material. Sodium carbonate is a white odorless powder or granule at room temperature. Sodium carbonate is easily soluble in water and glycerin, slightly soluble in absolute ethanol, and hardly soluble in propanol. The aqueous solution of sodium carbonate is alkaline and corrosive to a certain extent. It can undergo a metathesis reaction with acids, as well as some calcium salts and barium salts. The solution is alkaline, which can make phenolphthalein red. Mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization and food processing.
