Sodium carbonate (Na2CO3), molecular weight 105.99. The purity of the chemical is more than 99.5% (mass fraction), also known as soda ash, but the classification belongs to salt and does not belong to alkali. Also known in international trade as soda or soda ash., is a white, anhydrous, powdered or granular material. It is an essential raw material used in the manufacturing of glass, detergents chemicals and other industrial products. Soda ash is made in two main grades - light and dense. These have the same chemical properties and only differ in physical characteristics, such as bulk density and particle size and shape (which affect flow characteristics and angle of repose).
