The chemical formula is Na2CO3, commonly known as soda, soda ash, alkali ash, disodium carbonate salt, soda ash, usually a white powder, a strong electrolyte, density 2.532g/cm³, melting point of 851°C, easily soluble in water and glycerol, slightly soluble in anhydrous ethanol, insoluble in propyl alcohol, with the generality of the salt, belongs to the inorganic salt. Moist air will absorb moisture caking, partially changed to sodium bicarbonate. Sodium carbonate can be made by combined alkali method, ammonia alkali method, Lubran method, etc. It can also be refined by natural alkali 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 generally regarded as relatively harmless to the ecosystem. However, large discharges may still affect the pH and total alkalinity of water bodies and therefore require proper management and regulation in their use and disposal.
