    Soda ash is a colorless crystalline powder, soluble in water with heating, insoluble in most organic solvents. Hygroscopic. In the air, it absorbs moisture and carbon dioxide with the formation of an acidic salt NaHCO3; when stored in the open air, it cakes. Aqueous solutions are highly alkaline and form crystalline hydrates.
    Density: 2.53 g / cm³. Melting point 852 ° C.
    Chemical formula: Na2CO3.
    In nature, soda ash is found in the ash of some seaweed, as well as in the form of the following minerals: nahcolite, trona, sodium (soda), thermonatrite .
    Currently, an industrial method for producing soda ash is the so-called. Solvay way. Equimolar amounts of gaseous ammonia and carbon dioxide are passed into a saturated sodium chloride solution. The precipitated residue of poorly soluble sodium bicarbonate is filtered off and calcined (dehydrated) by heating to 140-160 ° C, while it passes into sodium carbonate. The formed carbon dioxide and ammonia, separated from the mother liquor at the first stage of the process, are returned to the production cycle by reaction.
    Depending on the purpose, technical soda ash manufactured in two grades: A (granular) and B (powder).
    - flue gas cleaning;
    - medium neutralization.
    Soda ash it is also used as a detergent, it removes grease well, softens water, and also neutralizes acidic components in drains. It is also used for softening water when washing and boiling fabrics, washing porcelain, earthenware, enamel dishes and other household purposes. The widely advertised Calgon descaling agent in washing machines consists of sodium tripolyphosphate and soda ash.
