The chemical formula of sodium carbonate is Na2CO3, also known as soda ash. It is usually a white powder, a strong electrolyte, with a density of 2.532g/cm3 and a melting point of 851 ° C. It is easily soluble in water and glycerol, slightly soluble in anhydrous ethanol, and difficult to dissolve in propanol. It has salt like properties and belongs to inorganic salts. Moist air can absorb moisture and form lumps, some of which turn into sodium bicarbonate.
The production methods of sodium carbonate include the combined alkali production method, ammonia alkali method, Lu Blan method, etc., and can also be refined by processing natural alkali.
As an important inorganic chemical raw material, it is mainly used in the production of flat glass, glass products, and ceramic glazes. It is also widely used in daily washing, acid neutralization, and food processing.
In terms of the environment, sodium carbonate is usually considered a relatively harmless substance to ecosystems.
