Appearance and Properties
It most commonly occurs as a crystalline decahydrate, which readily effloresces to form a white powder, the monohydrate. Pure sodium carbonate is a white, odorless powder that is hygroscopic (absorbs moisture from the air). It has a strongly alkaline taste, and forms a moderately basic solution in water.
Uses
Soda Ash light used as intermediate for dyestuff, paint synthesis, steel antiseptic and plastic intensifier. Soda Ash Dense mainly used in manufacturing of glass shell of kinescope and optic glass and float glass.
