Sodium carbonate is commonly known as soda, soda ash, soda ash, disodium carbonate, and soda ash. It is usually a white powder, a strong electrolyte, with a melting point of 851°C, easily soluble in water and glycerin, and is an inorganic salt.

Sodium carbonate can be produced by the combined alkali process, the ammonia-soda process, the Leblanc process, etc. It can also be processed and refined from natural alkali. 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 daily washing, acid neutralization and food processing. In terms of the environment, sodium carbonate is generally regarded as a relatively harmless substance to the ecosystem. However, large-scale discharges may still affect the pH value and total alkalinity of water bodies, so proper management and supervision are required during its use and disposal.
