Sodium carbonate is easily soluble in water and glycerol, 20 grams per 100 gram of water at 20℃, and the maximum solubility is 35.4℃. 49.7g of sodium carbonate is soluble in100g of water, slightly soluble in anhydrous ethanol, and hardly soluble in propanol.

Sodium carbonate aqueous solution is alkaline and corrosive. It can react with acids and some calcium salts and barium salts. The solution is alkaline and can turn phenolphthalein red.

Extended data:

Sodium carbonate can react with alkali such as calcium hydroxide and barium hydroxide to produce precipitate and sodium hydroxide. This reaction is usually used to prepare caustic soda in industry. Because sodium carbonate hydrolyzes in water to generate sodium hydroxide and carbonic acid, its reaction with some salts will push the chemical balance to move in the positive direction, generating corresponding alkali and carbon dioxide.

As one of the important chemical raw materials, sodium carbonate is widely used in light industry, daily chemicals, building materials, chemicals, food, metallurgy, textiles, petroleum, national defense, medicine and other fields. It is used as raw materials, cleaning agents and detergents for the manufacture of other chemicals, and also for photography and analysis.
