Sodium carbonate is an inorganic compound with a molecular formula of Na2CO3 and a molecular weight of 105.99. It is also called soda ash, but it is classified as salt, not alkali. The aqueous solution of sodium carbonate is alkaline and corrosive to a certain extent. It can undergo a metathesis reaction with acids, as well as some calcium salts and barium salts. The solution is alkaline, which can make phenolphthalein red. Also known as soda or soda ash in international trade. It is an important inorganic chemical raw material, 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.

1. It can be used in other sectors such as chemical industry and metallurgy. The use of heavy soda ash can reduce soda dust flying, reduce raw material consumption, improve working conditions, and improve product quality. At the same time, it can reduce the corrosion effect of alkali powder on refractories and extend the service life of the kiln.
2. As a buffer, neutralizer and dough improver, it can be used in cakes and pasta foods, and used in appropriate amounts according to production needs.
3. As detergent for wool rinsing, bath salt and medicine, alkali agent in leather tanning.
