True specific gravity 2.533 (20�°C), bulk density 0.90min. Easily soluble in water, Maximum solubility at 35.4�°C. The aqueous solution appears strong alkalinity. On exposure to air it easily absorbs moisture, carbon dioxide, and gradually forms sodium bicarbonate (caking soda). Usage: 1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass. 2. Soda ash also is used to clean the air and soften water. 3. Manufacture of Caustic Soda and dyestuffs 4. metallurgy (processing of steel and extraction of iron etc), 5. (flat glass, sanitary pottery) 6. national defense (TNT manufacturing, 60% gelatin-type dynamite ) and some other aspects, such as rock oil refining, paper manufacturing, paint, salt refining, softening of hard water, soap, medicine , food and so on.
Soda ash Sodium carbonate in scientific name, soda soda in common name, stone alkali, washing alkali, chemical formula Na2CO3, belonging to In salts, sodium carbonate containing ten crystal water is colorless crystal, crystal water is unstable, easy to weathering, It becomes a white powder Na2CO3, a strong electrolyte, with salt connectivity and thermal stability, easily soluble water, its aqueous solution is basic.
Sodium Carbonate (CAS No. 497-19-8) is an inorganic compound with a chemical formula of Na2CO3 and a molecular weight of 105.99. It is also called soda ash, but it is classified as a salt rather than an alkali. Also known as soda or soda ash in international trade Sodium carbonate is white odorless powder or granules at room temperature. It has water absorption, and gradually absorbs 1mol/L moisture (about = 15%) when exposed to the air. Sodium carbonate is easily soluble in water and glycerol. The aqueous solution of sodium carbonate is alkaline and corrosive to a certain extent and can undergo a metathesis reaction with acid, as well as a metathesis reaction with some calcium salts and barium salts. The solution is alkaline, which can make phenolphthalein turn red.

Soda ash, also known as sodium carbonate (Na2CO3), is an alkali chemical refined from the mineral trona or naturally occurring sodium carbonate-bearing brines (both referred to as natural soda ash), the mineral nahcolite (referred to as natural sodium bicarbonate, from which soda ash can be produced), or manufactured from one of several chemical processes (referred to as synthetic soda ash).
