Sodium chloride (Sodium chloride pwoder), is an inorganic ionic compound, chemical formula NaCl, colorless cubic crystal or fine crystalline powder, salty taste. The appearance is white crystals, and its source is mainly sea water, which is the main component of table salt.
Sodium chloride powder is easily soluble in water and glycerin, slightly soluble in ethanol (alcohol) and liquid ammonia; insoluble in concentrated hydrochloric acid. Impure sodium chloride is deliquescent in the air.
The stability is relatively good, and its aqueous solution is neutral. In industry, the method of electrolysis of saturated sodium chloride solution is generally used to produce hydrogen, chlorine, caustic soda (sodium hydroxide) and other chemical products (generally called chlor-alkali industry). It can also be used for ore Smelting (electrolysis of molten sodium chloride crystals to produce active sodium metal), medically used to prepare physiological saline, and daily life can be used as seasoning.
