Synonyms The anhydrous salt Na2C03 also is called Solvay soda and soda ash (technical grade is about 99% purity). The decahydrate Na2C03 IOH2O also is known as washing soda or sal soda. These two names usually refer to the technical product. Other synonyms for the decahydrate are soda and Nevite. ...

Soda ash is commercial anhydrous sodium carbonate. When a solution saturated at boiling temperature is allowed to cool to below 33°, a transparent crystalline mass separates of the formula Na2CC>3-10H2O, known commercially as soda crystals or sal soda.

Manufacture. Sodium carbonate is an important product of the alkali industry. It is obtained naturally by the purification of sal soda which is found in the water of lakes Magadi of Kenya in East Africa, Owens of California in the USA etc. Industrially it is obtained by the Solvay process (ammonia-soda process) sodium chloride solution is saturated by ammonia which is forced into the solution. Carbon dioxide gas is then blown into the solution to form the bicarbonate (NaHCO 3) and ammonium chloride (NH<,.C1). When the bicarbonate is separated and heated, water and carbon dioxide are driven off and sodium carbonate is obtained. The ammonium chloride is mixed with milk of lime and distilled to form calcium chloride and ammonia solution. The recovered ammonia is used repeatedly. 

Oxygen occurs in all kinds of minerals. Some common examples include the oxides, carbonates, nitrates, sulfates, and phosphates. Oxides are chemical compounds that contain oxygen and one other element. Calcium oxide, or lime or quicklime (CaO), is an example. Carbonates are compounds that contain oxygen, carbon, and at least one other element. Sodium carbonate, or soda, soda ash, or sal soda (Na2C03), is an example. It is often found in detergents and cleaning products.

The crude sodium carbonate from the Solvay process is quite pure, and is a low density (about 0.5g/cm ) fluffy material and referred to as light soda ash. The density may be increased to the l.Og/cm required for some uses by conversion to the monohydrate, NaiCOs HiO. The anhydrous light ash is tumbled with the appropriate quantity of water and then dried at <100°C. Sal soda (washing soda) is the decahydrate, NaiCOs lOHiO, which is obtained by crystallization of the light ash from water and drying at ambient temperatures (<35.5°C).

Solution of Chloride of Soda. To a solution of chloride of lime (formed of chloride of lime, h pound water, 3 pints), add a solution of carbonate of soda (formed of carbonate of soda, crystallized, 7 ounces water, 1 pint), and, after agitation for about 10 miimtes, decant or filter, and preserve tho filtrate in a well-stoppered bottle, and in a cool and dark place. This 1 the formula of the Dublin Pharmacopoeia, and often more convenient than tho preceding one. A writer in Boettger s Kotizblatt recommends that in preparing this solution from chloride of lime, bicarbonate of soda be used in place of sal-soda. There is no question but that the precipitate will bo much less bulky, and more of the liquid will be recovered in a concentrated form decantation.
