Sodium carbonate is soluble in water, glycerol, 20 degrees Celsius when one hundred grams of water can dissolve 20 grams of sodium carbonate, slightly soluble in anhydrous ethanol, insoluble in propanol. Sodium carbonate is a strong alkali salt, dissolved in water after the hydrolysis reaction (sodium carbonate hydrolysis will produce sodium bicarbonate and sodium hydroxide), so that the solution is alkaline, there is a certain degree of corrosiveness, and can be decomposed with the acid reaction (Na?CO?+H?SO?==Na?SO?+H?O+CO?↑), to produce the corresponding salt and release carbon dioxide.
Sodium carbonate is one of the important chemical raw materials, widely used in light industry, building materials, chemical industry, food industry, metallurgy, textiles, petroleum, national defense, medicine and other fields, used to manufacture other chemicals, cleaning agents, detergents, also used in the field of photography and analysis.
The vast majority used in industry, a small portion of civilian. In the industrial soda ash, mainly light industry, building materials, chemical industry, accounting for about 2/3; followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
