Soda Ash
Sodium carbonate (Na2CO3) has a molecular weight of 105.99, and its chemical purity is mostly above 99.5 (mass fraction). It is also called soda ash, but it is classified as salt, not alkali. 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.
Sodium carbonate is a white powder that is easily soluble in water. The solution is alkaline (it can make the phenolphthalein solution light red). It can be decomposed at high temperature and will not be decomposed by heating.
