Sodium carbonate [497-19-8] (Na2CO3), molecular weight 105.99. The purity of chemicals is mostly above 99.5% (mass fraction). 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.
