Soda soda, also called sodium carbonate, is an inorganic compound with the chemical formula of Na2CO3 and the molecular weight of 105.99, but it belongs to salt, not alkali. Also known as soda or soda ash in international trade. It is an important inorganic chemical raw material, which is mainly used to produce flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization and food processing.

Sodium carbonate (soda)

Sodium carbonate aqueous solution is alkaline, corrosive to some extent, and can react with acid and some calcium and barium salts. The solution is alkaline and can turn phenolphthalein red. Strong stability, but it can also be decomposed into sodium oxide and carbon dioxide at high temperature. Long-term exposure to the air can absorb moisture and carbon dioxide in the air, generate sodium bicarbonate and form lumps.

Sodium carbonate is a white and odorless powder or particle at room temperature. It has water absorption, and gradually absorbs 1mol/L of water when exposed to air (about = 15%). Its hydrates are sodium carbonate H2O, sodium carbonate 7H2O and sodium carbonate 10H2O. Solubility: Sodium carbonate is easily soluble in water and glycerol. 20g of sodium carbonate can be dissolved in100g of water at 20℃, and the maximum solubility is 35.4℃.
