Why is sodium chloride a strong electrolyte?
Sodium chloride is a strong electrolyte, according to the definition of a strong electrolyte: an electrolyte that is completely ionized into ions in an aqueous solution or in a molten state. Sodium chloride is completely ionized into ions in aqueous solution or molten state, so sodium chloride is a strong electrolyte.
The crystals of sodium chloride form stereosymmetry. In its crystal structure, the larger chloride ions are arranged in a cubic closest packing, and the smaller sodium ions fill the octahedral gaps between the chloride ions. Each ion is surrounded by six other ions. This structure also exists in many other compounds, known as sodium chloride structure or rock salt structure.
Sodium chloride is an inorganic ionic compound with the chemical formula NaCl, a colorless cubic crystal or fine crystalline powder, with a salty taste. The appearance is white crystal, and its source is mainly seawater, which is the main component of table salt. Soluble in water, glycerin, slightly soluble in ethanol (alcohol), liquid ammonia; insoluble in concentrated hydrochloric acid. Impure sodium chloride is deliquescent in the air.
Application of sodium chloride?
The stability of sodum chloride is relatively good, and its aqueous solution is neutral. it's widely used in many fields, follows are some for your review.
1. chlor-alkali 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.
2. disinfection and sterilization equipment, the method of electrolysis of dilute sodium chloride is generally to produce NaClO, ClO- ions are highly oxidizing, and can be used for the treatment of bacteria-containing sewage in hospitals, and can also be used for disinfection of swimming pools, domestic drinking water, domestic sewage, and tableware and drinking utensils in public canteens.
3. Other common fields: It can also be used for ore Smelting (electrolysis of molten sodium chloride crystals to produce active metal sodium), medically used to prepare saline, and used in daily life as seasoning.
