Sodium ntsev (6CI,7CI), yog ib qho inorganic ionic compound, tshuaj daim ntawv NaCl, tsis muaj xim cubic muaju los yog nplua crystalline hmoov, saj qab ntsev. Nws cov tsos yog dawb siv lead ua, nws qhov chaw yog dej hiav txwv, yog lub ntsiab ntawm ntsev. Soluble hauv dej, glycerin, me ntsis soluble hauv ethanol (cawv), kua ammonia; Insoluble nyob rau hauv concentrated hydrochloric acid. Impure sodium chloride yog deliquescent hauv huab cua. [1] yog ib qho kev ruaj ntseg zoo, nws cov tshuaj aqueous yog nruab nrab, kev lag luam feem ntau siv cov txheej txheem ntawm electrolytic saturated sodium chloride tov los tsim hydrogen, chlorine thiab caustic soda (sodium hydroxide) thiab lwm yam khoom siv tshuaj (feem ntau hu ua chlor-alkali kev lag luam) kuj tseem siv tau rau ore smelting, electrolysis ntawm molten sodium chloride siv lead ua cus ciav sodium hlau ntau lawm), kev kho mob siv los tsim physiological saline, Lub neej yuav siv tau rau seasoning.
Sodium ntsev (6CI, 7CI)lub cev muaj zog
Refraction tus nqi: 1.378

Stability: ruaj khov nyob rau hauv ib txwm thauj thiab tuav tej yam kev mob.
Cia tej yam kev mob: warehouse low temperature, cua, qhuav
Sodium ntsev (6CI, 7CI)Vapor siab: 1 mm Hg (865 ° C)
Sodium chloride yog cov hmoov dawb tsis muaj ntxhiab crystalline hmoov. Melting point 801 ℃, boiling point 1465 ℃, me ntsis soluble nyob rau hauv ethanol, propanol, butane, thiab butane tom qab kev sib nrig sib solubility rau hauv plasma, yooj yim soluble nyob rau hauv dej, dej solubility ntawm 35.9g (chav tsev kub). NaCl dispersion nyob rau hauv cawv tuaj yeem tsim colloid, nws solubility hauv dej yog txo los ntawm muaj hydrogen chloride, yuav luag insoluble nyob rau hauv concentrated hydrochloric acid. Tsis muaj ntxhiab tsw, qab ntsev, yooj yim deliquescence. Soluble hauv dej, soluble hauv glycerin, yuav luag insoluble hauv ether [3].
Cov khoom siv tshuaj
Cov qauv molecular
Cov crystals ntawm sodium chloride tsim steric symmetry. Hauv nws cov qauv siv lead ua, cov chloride ions loj dua tsim cov ntim ntim hnyav tshaj plaws, thaum cov sodium ions me me sau cov octahedral Qhov chaw nruab nrab ntawm cov chloride ions. Txhua ion yog surrounded los ntawm rau lwm ions. Cov qauv no kuj muaj nyob rau hauv ntau lwm cov tebchaw thiab hu ua sodium chloride hom qauv lossis pob zeb ntsev qauv.
