Sodium Salt (6CI,7CI), is an inorganic ionic compound, chemical form NaCl, colorless cubic crystals or fine crystalline powder, taste salty. Its appearance is white crystal, its source is mainly seawater, 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. [1] is a good stability, its aqueous solution is neutral, industry generally adopt the method of electrolytic saturated sodium chloride solution to produce hydrogen, chlorine and caustic soda (sodium hydroxide) and other chemical products (commonly known as chlor-alkali industry) can also be used for ore smelting, electrolysis of molten sodium chloride crystal lively sodium metal production), medical used to formulate physiological saline, Life can be used for seasoning.
Sodium salt (6CI,7CI) physical properties
Refraction rate: 1.378
Water solubility: 360 g/L (25 ºC)
Stability: stable under normal transport and handling conditions.
Storage conditions: warehouse low temperature, ventilation, dry
Sodium salt (6CI,7CI) Vapor pressure: 1 mm Hg (865 °C)
Sodium chloride is a white odorless crystalline powder. Melting point 801℃, boiling point 1465℃, slightly soluble in ethanol, propanol, butane, and butane after mutual solubility into plasma, easily soluble in water, water solubility of 35.9g (room temperature). NaCl dispersion in alcohol can form colloid, its solubility in water is reduced by the presence of hydrogen chloride, almost insoluble in concentrated hydrochloric acid. No odor, salty, easy deliquescence. Soluble in water, soluble in glycerin, almost insoluble in ether [3].
Chemical properties
The molecular structure
The crystals of sodium chloride form steric symmetry. In its crystal structure, the larger chloride ions form the most dense cubic packing, while the smaller sodium ions fill the octahedral Spaces between the chloride ions. Each ion is surrounded by six other ions. This structure is also found in many other compounds and is called the sodium chloride type structure or stone salt structure.
