The main uses of sodium carbonate:

Sodium carbonate, also called soda ash, is an inorganic compound. It is one of the important chemical raw materials and is widely used in light industry, daily chemicals, building materials, chemical industry, metallurgy, textiles, medicine and other fields; it is used as raw material, cleaning agent and detergent for manufacturing other chemicals; it is also used in photography technology and analytical fields; used in the food industry as neutralizing agent and leavening agent, such as making steamed buns, bread, etc.

The chemical formula of sodium carbonate is, Na2CO3+H2O=NaHCO3+NaOH. It is white odorless powder or granules at room temperature. It is hygroscopic and will gradually absorb moisture when exposed to the air. Easily soluble in water and glycerol, it can dissolve 20 grams of sodium carbonate per 100 grams of water at 20°C.

The aqueous solution of sodium carbonate is alkaline and corrosive to a certain extent. It can undergo metathesis reactions with acids, as well as with some calcium salts and barium salts. The solution is alkaline and can turn phenolphthalein red.

In addition, sodium carbonate has a wide range of uses, generally utilizing its alkalinity. It can be used to make glass, such as flat glass, bottle glass, optical glass and high-end utensils.

The reaction between fatty acids and sodium carbonate can also be used to make soap; in the softening of hard water, the refining of petroleum and oils, the removal of sulfur and phosphorus in the metallurgical industry, mineral processing, and copper, lead, nickel, and tin It is used in the preparation of uranium, aluminum and other metals, and in the chemical industry to prepare sodium salts, metal carbonates, bleaches, fillers, detergents, catalysts and dyes.

Sodium carbonate is also used in the preparation of refractory materials and glazes in the ceramic industry.
