sodium carbonate, chemical compound, Na2CO3, soluble in water and very slightly soluble in alcohol. Pure sodium carbonate is a white, odorless powder that absorbs moisture from the air, has an alkaline taste, and forms a strongly alkaline water solution.
Sodium bicarbonate is produced through the reaction of sodium carbonate, carbon dioxide, and water. The process involves saturating a solution of soda ash in a carbonating tower where compressed carbon dioxide is admitted counter-currently from the bottom.
