Relative Molecular Mass of Sodium Chloride: 58.4428

Introduction:

Sodium Chloride , an inorganic ionic compound with the chemical formula NaCl, is a colorless cubic crystal or fine crystalline powder with a salty taste. Appearance is white crystal-like, its source is mainly seawater, is the main component of table salt. Easily soluble in water, glycerol, slightly soluble in ethanol (alcohol), liquid ammonia; insoluble in concentrated hydrochloric acid. Impure sodium chloride has deliquescence in air.

Stability is relatively good, its aqueous solution is neutral, the industry generally uses electrolysis of 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 (electrolysis of molten sodium chloride crystals to produce active metal sodium), medical treatment is used to prepare saline, life can be used as a condiment.

Physical Properties:

Water Solubility: 360 g/L (25 ?C)

Stability: Stable under normal transportation and handling conditions.

Storage conditions: low temperature in the warehouse, ventilated, dry

Vapor pressure: 1 mm Hg ( 865 °C) ?

Sodium chloride is white odorless crystalline powder. Melting point 801 ° C, boiling point 1465 ° C, slightly soluble in ethanol, propanol, butane, in and butane mutual solubility into plasma, soluble in water, solubility in water is 35.9 g (room temperature).

NaCl dispersed in alcohol can form a colloid, its solubility in water is reduced by the presence of hydrogen chloride, almost insoluble in concentrated hydrochloric acid. Odorless and salty, easily deliquescent. Soluble in water, soluble in glycerol, almost insoluble in ether .
