Sodium carbonate (also named washing soda, soda ash and soda crystals, and in the monohydrate form as crystal carbonate), Na2CO3, is the water-soluble sodium salt of carbonic acid.
Pure sodium carbonate is 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.
Soda Ash has number of uses. Glass manufacturing is the largest application for soda ash, in the form of containers, fiberglass insulation, commercial building, and automotive industries.
Three grades of soda ash produced:
1. Dense Soda Ash: is an anhydrous substance. It forms an important industrial chemical, and widely used in the manufacture of different products.
2. Light Soda Ash: widely used as a pH regulator/ buffering agent in multiple industrial processes.
3. Washing soda: is an anhydrous substance that is produced by combining light soda ash along with additional molecules of water. It is used in soaps and washing detergents to improve their cleaning properties.
Soda ash also used to clean the air and soften water. As environmental concerns grow, demand increases for soda ash used in the removal of sulfur dioxide and hydrochloric acid from stack gases. Chemical producers use soda ash as an intermediate to manufacture products that sweeten soft drinks (corn sweeteners), relieve physical discomfort (sodium bicarbonate) and improve foods and toiletries (phosphates).

Soda Ash Light, also known as Sodium Carbonate (Na2CO3), is a type of soda ash with a lower density than dense soda ash.
Characteristics
1. Density: Soda Ash Light has a density of around 0.5-0.6 g/cm�³.
2. Appearance: It is a white, odorless powder.
3. Purity: Typically has a purity of 99.2% or higher.
Applications
1. Glass manufacturing: Soda Ash Light is used as a flux to reduce the melting point of silica, making it easier to produce glass.
2. Detergent manufacturing: It is used as a builder in detergent formulations to enhance cleaning power.
3. Paper manufacturing: Soda Ash Light is used to improve the brightness and strength of paper.
4. Textile industry: It is used as a dye fixative and to improve the colorfastness of textiles.

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).
