Vim li cas sodium chloride thiaj li muaj zog electrolyte?
Sodium chloride yog ib qho muaj zog electrolyte, raws li lub ntsiab lus ntawm ib tug muaj zog electrolyte: ib tug electrolyte uas yog kiag li ionized rau hauv ions nyob rau hauv ib tug aqueous tov los yog nyob rau hauv ib tug molten lub xeev. Sodium chloride yog kiag li ionized rau hauv ions nyob rau hauv aqueous tov los yog molten lub xeev, yog li sodium chloride yog ib tug muaj zog electrolyte.
Cov crystals ntawm sodium chloride tsim stereosymmetry. Nyob rau hauv nws cov qauv siv lead ua, cov chloride ions loj dua yog teem rau hauv lub cubic ze tshaj plaws ntim, thiab cov sodium ions me me sau cov octahedral khoob 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, hu ua sodium chloride qauv lossis pob zeb ntsev qauv.
Sodium chloride yog ib qho inorganic ionic compound nrog cov tshuaj formula NaCl, tsis muaj xim cubic siv lead ua los yog hmoov zoo crystalline hmoov, nrog rau qab ntsev. Cov tsos yog dawb siv lead ua, thiab nws qhov chaw yog dej hiav txwv, uas yog lub ntsiab lus ntawm cov ntsev 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.
Kev siv sodium chloride?
Kev ruaj ntseg ntawm sodum chloride yog qhov zoo, thiab nws cov tshuaj aqueous yog nruab nrab. nws tau siv dav hauv ntau qhov chaw, hauv qab no yog qee qhov rau koj qhov kev tshuaj xyuas.
1. chlor-alkali kev lag luam. Cov txheej txheem ntawm electrolysis ntawm saturated sodium chloride tov yog feem ntau siv los tsim hydrogen, chlorine, caustic soda (sodium hydroxide) thiab lwm yam khoom siv tshuaj.
2. Cov khoom siv tshuaj tua kab mob thiab ua kom tsis muaj menyuam, cov txheej txheem ntawm electrolysis ntawm dilute sodium chloride feem ntau yog los tsim NaClO, ClO- ions yog oxidizing heev, thiab tuaj yeem siv rau kev kho cov kab mob uas muaj cov dej phwj hauv tsev kho mob, thiab tseem tuaj yeem siv rau kev tua kab mob ntawm cov pas dej da dej, cov dej haus hauv tsev, cov dej phwj hauv tsev, thiab cov tais diav thiab cov khoom siv hauv tsev noj mov.
3. Lwm yam kev lag luam: Nws kuj tseem siv tau rau ore Smelting (electrolysis ntawm molten sodium chloride crystals los tsim active hlau sodium), kev kho mob siv los npaj saline, thiab siv nyob rau hauv lub neej txhua hnub raws li seasoning.
