Thaum cov hluav taws xob tam sim no dhau los ntawm kev daws teeb meem ntawm sodium chloride ntsev ces hydrogen gas yuav raug ntsuas ntawm qhov tsis zoo electrode piv txwv li cathode, thiab cov roj chlorine yuav tsim ntawm qhov zoo electrode piv txwv li anode. Ntawm anode cov tshuaj tiv thaiv yog li: $2C{l^ - } to C{l_2} + 2{e^ - }$.
Qhov twg tshwm sim ntawm anode thaum lub sij hawm electrolysis ntawm fused NaCl?
Hint: Cov electrolysis ntawm fused NaCl yog siv rau kev tsim cov hlau Na. Oxidation tshwm sim ntawm anode thiab txo qis yuav tshwm sim ntawm cathode.
Nws yog tsim los ntawm electrolysis ntawm fused NaCl:-?
》Plag - Thaum lub sij hawm electrolysis ntawm fused sodium chloride, sodium uas tsim an Cation yog tso rau hauv Cathode thiab chlorine uas tsim cov anion tso ntawm anode. Yog li, los ntawm cov tshuaj tiv thaiv no, peb tuaj yeem hais tias Na yog hloov zuj zus ntawm Cathode.
Qhov twg tshwm sim ntawm anode thaum lub sij hawm electrolysis?
Cov tshuaj tiv thaiv ntawm lub anode yog oxidation thiab qhov ntawm cathode yog txo. Ntawm no, lub anode yog qhov zoo thiab cathode yog qhov tsis zoo electrode. Cov tshuaj tiv thaiv ntawm anode yog oxidation thiab hais tias ntawm cathode yog txo. Cov electrons yog muab los ntawm hom tau oxidized.
Nyob rau hauv cov txheej txheem twg fused NaCl yog Electrolysed?
Sodium hlau yog muab rho tawm los ntawm "Cov Txheej Txheem", ntawm kev lag luam. -Down tus txheej txheem yog raws li lub hauv paus ntsiab lus ntawm electrolysis ntawmfused los yog molten Sodium Chloride (NaCl). Down lub cell nyob rau hauv uas cov txheej txheem no tshwm sim, muaj ib lub thawv ntawm steel.
