Nov 23, 2017

CAS No.: 497-19-8
EINECS 231-867-5
The manufacture of glass is one of the most important uses of sodium carbonate. Sodium carbonate is also used as a relatively strong base in various settings. For example, sodium carbonate is used as a pH regulator to maintain stable alkaline conditions necessary for the action of the majority of photographic film developing agents.
It is a common additive in municipal pools used to neutralize the corrosive effects ofchlorine and raise pH.
In cooking, it is sometimes used in place of sodium hydroxide for lyeing, especially with German pretzels and lye rolls.
In chemistry, it is often used as an electrolyte.

Super grade
Some Items Are Superior To The National Standard
Total Base Content(As Na2co3 On Dry Base)%99.2min
Chloride(As Nacl, On Dry Base)%0.70max
Iron(As Fe, On Dry Base)%0.0035max
Insoluble Matter In Water%0.03max

Property: White powdered crystal, 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).
Uses: Soda ash is one of the basic materials for chemical industry, mainly used for metallurgy, glass, textile, dye printing, medicine, synthetic detergent, petroleum and food industry etc.
