Read： 507 Time：19months ago Source：Transform the World with Simplicity

Sodium carbonate, also known as soda ash or soda, is a very important inorganic chemical raw materials, widely used in the field of chemical production. This article will detail the properties and uses of sodium carbonate.

1. the nature of sodium carbonate

sodium carbonate is a white powder with strong alkalinity. It is readily soluble in water and its aqueous solution is alkaline. Sodium carbonate is also hygroscopic and can absorb moisture in the air. In addition, sodium carbonate decomposes at high temperatures to produce sodium oxide and carbon dioxide.

2. the use of sodium carbonate

1. glass manufacturing: sodium carbonate is one of the main raw materials in glass manufacturing, can be made with quartz sand, limestone and other raw materials together with the melting of glass.
2. Soap and Detergent Production: Sodium carbonate can be used to produce soaps and detergents because of its detergency and emulsification.
3. Food industry: Sodium carbonate can be used in food processing, such as baking food as a leavening agent, and used in the production of MSG and other condiments.
4. Chemical production: Sodium carbonate can be used as a raw material in chemical production and used to produce many other compounds, such as sodium hydroxide, hydrochloric acid, hydrogen peroxide, etc.
5. Metallurgical industry: Sodium carbonate can be used as a flux in the metallurgical industry to extract metals.

In short, sodium carbonate, as an important chemical raw material, has been widely used in glass manufacturing, soap and detergent production, food industry, chemical production and metallurgical industry.
