The electronic formula of sodium chloride is shown below:

Sodium chloride (Sodium chloride), chemical formula NaCl, colorless cubic crystals or fine crystalline powder, taste salty. Appearance is white crystalline, its source is mainly seawater, is the main component of table salt.

Physical properties: melting point 801 ° C, boiling point 1465 ° C, slightly soluble in ethanol, propanol, butane, and butane in the mutual solubility of plasma, easily soluble in water, solubility in water is 35.9 g (room temperature). Impure sodium chloride has deliquescence in air.

Chemical properties: Sodium chloride (Sodium chloride), chemical formula NaCl, sodium chloride crystals form steric symmetry.

1, Electrolysis of molten sodium chloride to make sodium metal

2, Electrolysis of brine

3, Reaction with silver nitrate

4, Reaction with concentrated sulfuric acid (laboratory production of hydrogen chloride)

(concentrated stands for concentrated, and excess stands for excess)

Extended information

Sodium chloride applications:

Uses:

1, industry generally uses electrolysis of saturated sodium chloride solution to produce hydrogen, chlorine, and caustic soda (sodium hydroxide) and other chemicals (generally known as the chlor-alkali industry) can also be used in ore smelting (electrolysis of molten sodium chloride crystals to produce active metal sodium).

2, the food industry and fisheries for salt curing, but also used as raw materials for seasoning and refined salt. Adding salt in cooking dishes can remove some of the odor of the raw materials and increase the taste.

3, medical used to configure saline. Sodium chloride is indispensable. The physiological functions of sodium ion and chloride ion are: to maintain the osmotic pressure of extracellular fluid; to participate in the regulation of acid-base balance in the body; chloride ion in the body to participate in the generation of gastric acid.

4. 4. In agriculture, aqueous sodium chloride solution can be used for seed selection. Configure the NaCl solution according to the needs of the species, which is denser than water. Seeds are put into the NaCl solution, the floating ones are not full, and the sinking ones are full.
