Soda Ash / Sodium Carbonate

Soda Ash is anhydrous salt form of sodium carbonate. It is the common name for sodium carbonate, which separates calcium into sodium and carbonate ions in solution.  It is also known as washing soda with molecular formula (Na2CO3). Soda Ash possess inherent properties which make it used as component on largescale in domestic and industrial products. Soda Ash is found in white powder as well as granules and is odorless alkali chemical solution in water.


There are two main types of soda ash:

  • Dense Soda Ash

  • Light Soda Ash

General Description

  • Light soda ash is perfectly fine. In fact, it is the normal grade of soda ash that is sold by dye suppliers.

  • There are two main grades of soda ash, light and dense. Both have the same molecular weight (105.99), have the same solubility (maximum 33.2% at 35.4°C), and produce the same pH when measured by weight (a 1% solution in plain distilled water is supposed to produce a pH of 11.4).

  • The difference between the grades lies in density and particle size and Production method. Generally, the density of soda ash light is 500-600kg/m3, the density of soda ash dense is 1000-1200kg/m3.

  • Price difference: soda ash dense is higher than light


  • Manufacture of glass, where it reduces the melting temperature of the sand used in glass formation and helps in the 'workability' or shaping of glass articles such as tableware and float glass,

  • Making soaps and detergents, where it is employed as a builder, or filler, to give a smoother surface,

  • Production of chemicals such as sodium silicate, sodium bicarbonate and percarbonate, and sodium chromate and dichromate,

  • Pulp and paper manufacture, water treatment, effluent treatment, metallurgy and drugs. 

  • Ph Controller.

  • Food Manufacturing.

  • Oil Drilling: additive for drilling and work-over fluids to treat Calcium.

  • Water Treatment.
