Sodium Chloride

Sodium chloride is an inorganic ionic compound with the chemical formula NaCl, colorless cubic crystal or fine crystalline powder, salty taste. The appearance is white crystalline, and its source is mainly seawater, which is the main component of salt. Soluble in water, glycerin, slightly soluble in ethanol (alcohol), liquid ammonia; Insoluble in concentrated hydrochloric acid. Impure sodium chloride is deliquescent in air. Its stability is relatively good, and its aqueous solution is neutral. Industry generally uses the method of electrolytic saturated sodium chloride solution to produce hydrogen, chlorine and caustic soda (sodium hydroxide) and other chemical products (generally known as chlor-alkali industry), can also be used for ore smelting (electrolytic molten sodium chloride crystals to produce active sodium metal), medical use to prepare normal saline, life can be used for condiments

Sodium chloride is a white odorless crystalline powder. Melting point 801℃, boiling point 1465℃, slightly soluble in ethanol, propanol, butane, and butane after miscible into plasma, easily soluble in water, water solubility of 35.9 g/100g water (room temperature). NaCl dispersed in alcohol can form colloids, its solubility in water is reduced by the presence of hydrogen chloride, and it is almost insoluble in concentrated hydrochloric acid. No smell salty, easy deliquination. Soluble in glycerol, 1 g of sodium chloride soluble in 10 ml glycerol, almost insoluble in ether

In the crystal structure of sodium chloride, the larger chloride ions are arranged in the cubic most densely packed, and the smaller sodium ions fill the octahedral Spaces between the chloride ions. Each ion is surrounded by six other ions. This structure also exists in many other compounds, called sodium chloride type structure or stone salt structure.
