Usawoti Wesodium (6CI,7CI), iyinhlanganisela ye-ionic ye-inorganic, ifomu lamakhemikhali i-NaCl, amakristalu e-cubic angenambala noma impushana ecwebezelayo ecwebezelayo, ukunambitha okusawoti. Ukubukeka kwayo kuyikristalu emhlophe, umthombo wayo ikakhulukazi amanzi olwandle, yiyona ingxenye eyinhloko kasawoti. Incibilika emanzini, i-glycerin, i-soluble kancane ku-ethanol (utshwala), i-ammonia ewuketshezi; Ayincibiliki ku-concentrate hydrochloric acid. I-sodium chloride engcolile inobuthi emoyeni. [1] iwukuzinza okuhle, isixazululo saso esinamanzi asithathi hlangothi, imboni ngokuvamile isebenzisa indlela ye-electrolytic saturated sodium chloride solution ukukhiqiza i-hydrogen, i-chlorine ne-caustic soda (i-sodium hydroxide) neminye imikhiqizo yamakhemikhali (eyaziwa kakhulu ngokuthi imboni ye-chlor-alkali) ingabuye isetshenziselwe ukuncibilikisa insimbi, i-electrolysis yokukhiqizwa kwensimbi encibilikisiwe ye-sodium chloride crystal ephilayo ye-sodium), ukwelashwa okusetshenziselwa ukwenza usawoti wokuphila, Impilo ingasetshenziselwa isinongo.
Usawoti we-sodium (6CI,7CI)izakhiwo zomzimba
Izinga lokuhlehlisa: 1.378
Ukunyibilika kwamanzi: 360 g/L (25 ºC)
Ukuzinza: ukuzinza ngaphansi kwezimo zokuthutha ezivamile kanye nokusingatha.
Izimo zokugcina: izinga lokushisa eliphansi leshede, umoya omncane, owomile
Usawoti we-sodium (6CI,7CI)Ukucindezela komhwamuko: 1 mm Hg (865 °C)
I-sodium chloride iyimpushana eyikristale engenaphunga emhlophe. Iphuzu elincibilikayo elingu-801℃, iphoyinti elibilayo elingu-1465℃, lincibilika kancane ku-ethanol, i-propanol, i-butane, ne-butane ngemva kokuncibilika okufanayo ku-plasma, inyibilika kalula emanzini, ukunyibilika kwamanzi okungu-35.9g (izinga lokushisa legumbi). Ukuhlakazwa kwe-NaCl otshwaleni kungakha i-colloid, ukuncibilika kwayo emanzini kuncishiswa ngokuba khona kwe-hydrogen chloride, cishe engancibiliki ku-concentrated hydrochloric acid. Alikho iphunga, linosawoti, ubumuncu obulula. Incibilika emanzini, incibilika ku-glycerin, icishe ingancibiliki ku-ether [3].
Izakhiwo zamakhemikhali
Isakhiwo samangqamuzana
Amakristalu e-sodium chloride enza i-steric symmetry. Esimisweni sayo sekristalu, ama-ion e-chloride amakhulu akha ama-cubic aminyene kakhulu, kuyilapho ama-ion amancane e-sodium egcwalisa izikhala ze-octahedral phakathi kwama-ion e-chloride. I-ion ngayinye izungezwe amanye ama-ion ayisithupha. Lesi sakhiwo sitholakala nakwezinye izinhlanganisela eziningi futhi sibizwa ngokuthi isakhiwo sohlobo lwe-sodium chloride noma isakhiwo sikasawoti wamatshe.
