Sodium chloride is the main component of table salt and rock salt, which is an ionic compound, colorless and transparent cubic crystal. Sodium oxide exists in large quantities in seawater and natural salt lakes. It can be used to prepare chlorine, hydrogen, hydrochloric acid, sodium hydroxide, chlorate, hypochlorite, bleaching powder and sodium metal, etc. It is an important chemical raw material; it can be used for food seasoning. And pickled fish and vegetables, as well as for salting out soap and tanning leather, etc.; highly refined sodium chloride can be used to make physiological food Chemicalbook brine for clinical treatment and physiological experiments, such as sodium loss, water loss, blood loss and so on. Sodium chloride can be produced by concentrating crystalline seawater or natural salt lake or salt well water.
Application:
Sodium chloride is an important chemical raw material for the preparation of chlorine, sodium metal, caustic soda, soda ash and other substances, and is widely used in dyes, ceramics, metallurgy, leather, soap, freezing and so on. In analytical chemistry, sodium chloride is a reagent for the determination of fluorine and silicate, and a reference reagent for the calibration of silver nitrate.
