Na2CO3 is the molecular formula for sodium carbonate. It is either found naturally or is manufactured from sodium chloride. Sodium carbonate is a white, odorless powder and is one of the most basic industrial chemicals.
One of the most important uses for sodium carbonate is in the manufacture of glass, where it is used as a flux in the melting of silica. In chemistry, sodium carbonate is often used as an electrolyte. In dyeing it is used to ensure proper chemical bonding of the dye with the fibers. In domestic use, it can soften hard water during laundry. It can also replace sodium hydroxide in cooking.
