Lo lus teb yog qhov kev xaiv (iii) Lub xov tooj hluav taws xob hluav taws xob tuaj yeem coj tus cwj pwm zoo li lub xov tooj hluav taws xob thaum muaj ib qho kev thov ntawm ib qho kev cuam tshuam sab nraud ntawm lub galvanic cell thiab cov tshuaj tiv thaiv tsis yog inhibited kom txog thaum qhov tawm tsam qhov hluav taws xob nce mus txog tus nqi 1.1 V. Tsis muaj tam sim no ntws los ntawm lub xov tooj thaum qhov no tshwm sim.
Thaum lub xovtooj hluav taws xob ua haujlwm zoo li lub xovtooj ntawm electrolytic?
Vim li no, kev xaiv c) ${E_{Ext}} > {E_{cell}}$ yog cov lus teb raug yog thaum lub xov tooj hluav taws xob tuaj yeem coj tus cwj pwm zoo li electrolytic cell. Lus Cim: Hauv ob qho tib si electrochemical thiab electrolytic hlwb, oxidation tseem nyob ntawm anode thiab qhov txo qis tseem tshwm sim ntawm cathode tab sis cov polarities ntawm ob lub electrodes yog thim rov qab.
Ib qho hluav taws xob hluav taws xob puas ua tau raws li cov xov tooj hluav taws xob?
Yes, lub xov tooj hluav taws xob hluav taws xob tuaj yeem ua raws li cov xov tooj hluav taws xob yog tias muaj qhov sib txawv ntau dua li qhov muaj peev xwm ntawm cov hluav taws xob hluav taws xob tau siv. Nyob rau hauv cov ntaub ntawv no, cov tshuaj tiv thaiv pib mus rau qhov opposite kev taw qhia, uas yog, cov tshuaj tiv thaiv uas tsis yog-spontaneous tshwm sim zoo li nyob rau hauv ib tug electrolytic cell.
Yuav ua li cas koj tuaj yeem hloov cov hluav taws xob hluav taws xob rau hauv cov hluav taws xob hluav taws xob?
Electrolytic cells tsis tshwm sim nws tus kheej thiab yog li yuav tsum muaj lub zog muab. Txhawm rau ua kom lub cell galvanic xav tau lub zog, hloov lub anode thiab cathode. Ua kom cov tshuaj tiv thaiv rov qab.
Ib tug electrochemical cell thetib yam li electrolytic cell?
Electrochemical cells hloov tshuaj lub zog rau hauv hluav taws xob lub zog lossis rov ua dua. Electrolytic cell yog ib hom electrochemical cell uas hluav taws xob hluav taws xob hloov mus rau hauv hluav taws xob tshuaj. … Electrolytic cells muaj qhov zoo them anode thiab cov cathode tsis zoo.
