White powder, is solid
Taste: Acerbity
The relative density (water = 1)
Melting point: 851Degrees Celsius
Solubility: 21g 20 Degrees Celsius

Stability:
Stability stronger, but high temperatures also can decompose, generating oxidation sodium and carbon dioxide. Long-term exposure to air can absorbs moisture from the air and carbon dioxide, generating sodium bicarbonate, and form lumps. Hygroscopic very strong, very easy to form lumps, at high temperatures also does not decompose.

Solubility:
Soluble in water, soluble in anhydrous alcohol, insoluble in propanol. Sodium carbonate is soluble in water, is a kind of alkali salt, soluble in water occurs after hydrolysis reaction, make explicit alkaline solution, has certain corrosive, can with acid on neutralization reaction, generating the corresponding salt and releasing carbon dioxide.

Use:
Is one of the important chemical raw materials, for making chemicals, cleaning agents, detergent, also used in neuroscientists have and making pharmaceuticals.
Most used in industry, a small part for civilian use. In industrial use soda, mainly is light industry, building materials, chemical industry, accounting for approximately 2/3; Followed by metallurgical, textile, oil, national defense, pharmaceutical and other industries. Glass industry is the biggest soda consumption departments, every tons of glass consumption soda 0.2 tons. Chemical industry for making the sodium silicate, sodium dichromate, sodium nitrate and sodium fluoride, baking soda, borax, trisodium phosphate, sodium etc. The metallurgical industry as smelting flux, dressing collectorless flotation agents, steelmaking and refined antimony used desulphurization agent. Dyeing industry as soft agent. Leather industry for raw material leather degreasing, neutralization chrome tanning and improve chrome tanned liquid alkalinity. Also used in the production of synthetic detergent additives sodium tripolyph-osphate and other sodium salt, etc. Consumption level of soda for the production monosodium glutamate, pasta, etc.

Health hazard:
This product has the weak stimulating and weak corrosive. Direct contact can cause skin and eye burns. Production of inhaled its dust and smoke can cause irritation to the respiratory tract and conjunctivitis, still can have nasal mucosa ulcer and atrophy and septal perforation. Long time to contact the product solution can happen eczema, dermatitis, corn shape ulcer and flabby skin. Contact with the product of exposed workers in respiratory diseases increased incidence. Accidental can cause gastrointestinal burns, mucous membrane debaucjed, bleeding and shock.
