Qhov sib txawv tseem ceeb ntawm hluav taws xob thiab ionic conduction yog cov hluav taws xob conduction yog kev txav ntawm electrons los ntawm ib qho chaw mus rau lwm qhov, whereas ionic conduction yog txav ntawm ions ntawm ib qho chaw mus rau lwm qhov.
Lub sij hawm conduction yog hais txog kev hloov ntawm lub zog los ntawm ib yam khoom. Ntawm no, lub zog tuaj yeem hloov pauv hauv ntau hom xws li cua sov thiab hluav taws xob. Electronic conduction thiab ionic conduction yog ob hom kev hloov hluav taws xob uas tau muab faib ua raws li qhov nruab nrab ntawm kev coj ua.
Kev coj hluav taws xob yog dab tsi?
Hluav taws xob conduction yog cov txheej txheem ntawm kev hloov hluav taws xob nyob rau hauv daim ntawv ntawm hluav taws xob tam sim no. Ntawm no, txoj kev conduction yog electron txav. Txawm li cas los xij, ib qho hluav taws xob hauv txhua qhov system tsis tuaj yeem ua rau txoj kev coj ua no. Cov hluav taws xob yuav tsum nyob hauv lub xeev dawb thiaj li txav ntawm ib qho mus rau lwm qhov. Lub plhaub sab hauv electrons ntawm atoms txav tsis tau. Lwm qhov yuav tsum tau muaj yog qhov muaj hluav taws xob uas tuaj yeem ua rau lub zog ntawm cov hluav taws xob dawb.
Daim duab 01: Kev Siv Hluav Taws Xob
Electrons uas muaj peev xwm ua tau raug hu ua "conduction electrons". Cov electrons no tsis ruaj khov rau ib qho atom lossis molecule. Cov electrons dawb no tuaj yeem dhia ntawm lub orbital ntawm ib lub atom mus rau lub orbital ntawm ib qho atom uas nyob ib sab. Txawm li cas los xij, tag nrho, cov electrons no khi rau tus neeg xyuas pib. Lub zog ntawm electrons pib nrog kev siv hluav taws xob. Lub teb hluav taws xob muab cov electrons txav mus.
Ionic Kev coj ua yog dab tsi?
Ionic conduction yog txheej txheem ntawm kev hloov lub zog ntawm kev txav ntawm hom ionic. Thaum lub sij hawm ionic conduction, ntau hom ionic txav ntawm ib qho chaw mus rau lwm qhov chaw raws li ionic gradient. Ib tug ion yog ib hom nqi them; nws tuaj yeem raug them nyiaj zoo lossis tsis zoo. Positively charged ions txav mus rau qhov chaw tsis zoo thiab rov ua dua. Qhov kev nyiam ntawm ib yam khoom mus rau ionic conduction yog ntsuas raws li ionic conductivity. Nws yog denoted los ntawm λ.
Daim duab 02: Ib lub cell membrane siv nyob rau hauv electrolysis ntawm brine tov qhov twg ionic conduction tshwm sim los ntawm daim nyias nyias ntawm nruab nrab kom cov ionic concentrations ruaj khov.
Feem ntau, peb siv lo lus ionic conduction hais txog siv lead ua lattices. Ntawm no, ionic conduction yog hais txog kev txav ntawm ions los ntawm ib qho tsis xws luag mus rau lwm qhov hauv cov iav siv lead ua. Tus txheej txheem ntawm conduction ntawm ions yog ib tug mechanism ntawm tam sim no uas lub zog yog kis los ntawm ib qho chaw mus rau lwm qhov.
Qhov txawv ntawm Kev Siv Hluav Taws Xob thiab Ionic yog dab tsi?
Hluav taws xob conduction thiab ionic conduction yog ob hom kev hloov hluav taws xob uas tau muab cais raws li qhov nruab nrab ntawm kev coj ua. Qhov sib txawv tseem ceeb ntawm hluav taws xob thiab ionic conduction yog qhov hluav taws xob conduction yog kev txav ntawm electrons los ntawm ib qho chaw mus rau lwm qhov, whereas ionic conduction yog kev txav ntawm ions ntawm ib qho mus rau lwm qhov.
Hauv qab no yog cov lus qhia txog qhov sib txawv ntawm hluav taws xob thiab ionic conduction.
Summary – Electronic vs Ionic Conduction
Hluav taws xob conduction thiab ionic conduction yog ob hom kev hloov hluav taws xob uas tau muab cais raws li qhov nruab nrab ntawm kev coj ua. Qhov sib txawv tseem ceeb ntawm hluav taws xob thiab ionic conduction yog qhov hluav taws xob conduction yog kev txav ntawm electrons los ntawm ib qho chaw mus rau lwm qhov, whereas ionic conduction yog kev txav ntawm ions ntawm ib qho mus rau lwm qhov.
