Cov ions tsis tuaj yeem txav mus los ua cov hluav taws xob tam sim no. Tab sis thaum lub ionic compound melts, cov ions them dawb txav mus. Yog li ntawd, molten ionic compounds ua hluav taws xob.
Puas molten sodium ua hluav taws xob?
Molten s alts ua hluav taws xob tib yam uas lawv ua thaum lawv yaj hauv dej; Qee cov ntsev molecules yog dissociated rau hauv ions, uas tso cai rau cov ions ua hluav taws xob. Lub "Downs Cell" capitalizes ntawm no conduction ntawm hluav taws xob los tsim tag nrho cov hlau sodium uas yuav tsum tau los ntawm kev lag luam.
Puas yog molten sodium chloride zoo conductor ntawm hluav taws xob?
Raws li kev txav ntawm ib tus neeg atoms lossis cov molecules hauv cov kua hauv lub xeev muaj ntau dua li cov khoom, cov ions (Na + & Cl−) yog dawb txav thiab yog li tuaj yeem ua raws li tus neeg nqa khoom. Li no molten sodium chloride yog tus neeg xyuas pib zoo ntawm hluav taws xob vim tsis muaj ions dawb.
Puas yog molten sodium chloride yog tus neeg xyuas pib lossis cov insulator?
khoom NaCl yog ib qho insulator tab sis molten NaCl yog ib qho zoo conductor ntawm hluav taws xob. Sodium Chloride muaj cov qauv crystalline uas cov ions zoo thiab tsis zoo yog tuav los ntawm cov hluav taws xob muaj zog heev ntawm kev nyiam. Li no tsis muaj cov hluav taws xob dawb txav mus los vim nws yog ib qho insulator.
NaCl puas ua hluav taws xob hauv lub xeev molten?
Electrons raug khi rau hauv daim ntawv cog lus los ntawm kev muaj zogelectrostatic zog. Yog li, sodium chloride tsis ua hluav taws xob nyob rau hauv lub xeev solid-state. Nyob rau hauv ib lub xeev molten, sodium chloride dissociates rauib sodium ion thiab chloride ion thiab cov ions ua hluav taws xob.
