CLASSIFICATION
GENERAL DESCRIPTION
Sodium Carbonate is a white, crystalline compound soluble in water (absorbing moisture from the air) but insoluble in alcohol. It forms a strongly alkaline water solution. Soda ash is the industrial name of anhydrous sodium carbonate. Sodium carbonate decahydrate, a colorless, transparent crystalline compound, is commercially called sal soda or washing soda. Soda Ash is produced synthetically using the Ammonia Soda process (Solvay process) treating sodium chloride with ammonia and carbon dioxide. Trona, a naturally occurring mineral, is used also as a source of sodium carbonate. It is is an essential ingredient in many industrial and manufacturing processes. It has a wide range of industrial uses, being crucial in the manufacture of flat and container glass and a key ingredient in the production of detergents. It is also used in water purification, polymer production, tanning, aerospace alloys, paper manufacturing process, effluent neutralisation, metal refining, sugar extraction and cement manufacture.
