What is Sodium Carbonate

The chemical formula is Na2CO3, commonly known as soda, soda ash, alkali ash, disodium carbonate salt, soda ash, usually white powder, strong electrolyte, density of 2.532g/cm3, melting point of 851 °C, soluble in water and glycerol, slightly soluble in anhydrous ethanol, insoluble in propanol [10], with the general properties of salt, belongs to inorganic salt. In the humid air, it will absorb moisture and agglomerate, and some of it will become sodium bicarbonate. The preparation methods of sodium carbonate include the combined alkali production method [12], the ammonia-alkali method [11], the Lubran method [13], etc., and can also be refined by trona processing. As an important inorganic chemical raw material, it is mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization, and food processing. In terms of the environment, sodium carbonate is often regarded as a relatively harmless substance to the ecosystem. However, large discharges can still affect the pH and total alkalinity of water bodies, so proper management and regulation are required when used and treated.
