high purity of soda ash light and dense CAS 497-19-8 for detergent application
Sodium carbonate (also known as washing soda, soda ash and soda
in the monohydrate form as crystal carbonate), Na2CO3, is the
sodium salt of carbonic acid.
It most commonly occurs as a crystalline decahydrate, which readily
form a white powder, the monohydrate. Pure sodium carbonate is a
powder that is hygroscopic (absorbs moisture from the air). It has
alkaline taste, and forms a moderately basic solution in water.
Sodium carbonate is
well known domestically for its everyday use as a water softener.
Historically it was
extracted from the ashes of plants growing in sodium-rich soils,
such as vegetation
from the Middle East, kelp from Scotland and seaweed from Spain.
ashes of these sodium-rich plants were noticeably different from
ashes of timber
(used to create potash), they became known as "soda ash". It is
produced in large quantities from salt (sodium chloride) and
limestone by a method
known as the Solvay process.

By far the largest consumption of sodium carbonate is in the
manufacture of glass,
paper, rayon, soaps, and detergents. It is also used as a water
carbonate can precipitate the calcium and magnesium ions present in
Sodium carbonate is a food additive (E500) used as an acidity
agent, raising agent, and stabilizer. It is one of the components
of kansui , a
solution of alkaline salts used to give ramen noodles their
characteristic flavor and
texture. It is also used in the production of snus (Swedish-style
snuff) to stabilize
the pH of the final product.
Sodium carbonate is also used in the production of sherbet powder.
and fizzing sensation results from the endothermic reaction between
carbonate and a weak acid, commonly citric acid, releasing carbon
which occurs when the sherbet is moistened by saliva.
In China, it is used to replace lye-water in the crust of
traditional Cantonese moon
cakes, and in many other Chinese steamed buns and noodles.
Sodium carbonate is used by the brick industry as a wetting agent
to reduce the
amount of water needed to extrude the clay.
