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.
Light / Dense Soda Ash
Sodium Carbonate (Na2CO3), commonly known as Soda Ash, may well have been the third "industrial chemical" used by man; perhaps employed sometime after salt (NaCl) and lime (CaO).

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.
