ob hom
Yog li ntawd, dab tsi yog 2 hom electrochemical hlwb?
Ob hom ntawm Cell Muaj ob tsim nyog hom electrochemical cell : galvanic thiab electrolytic. Galvanic hlwb hloov tshuaj muaj peev xwm zog rau hauv hluav taws xob hluav taws xob. Lub zog hloov dua siab tshiab yog ua tiav los ntawm tus kheej (ΔG < 0) cov tshuaj tiv thaiv redox uas tsim cov dej ntws ntawm electrons.
Tsis tas li ntawd, dab tsi yog ob lub ntsiab lus tseem ceeb ntawm electrochemical cell? Electrochemical hlwb muaj ob conductive electrodes, hu ua anode thiab cathode. Lub anode txhais tau tias yog electrode qhov twg oxidation tshwm sim. Lub cathode yog lub electrode uas txo qhov chaw.
Hauv qhov no, lub npe nrov rau lub xov tooj hluav taws xob electrochemical yog dab tsi?
Cov electrochemical hlwb uas tsim hluav taws xob tam sim no hu ua voltaic cell los yog galvanic hlwb thiab cov uas tsim cov tshuaj tiv thaiv, los ntawm electrolysis piv txwv li, hu ua electrolytic hlwb . A feem ntau piv txwv ntawm galvanic cell yog tus qauv 1.5 volt cell txhais tau tias siv rau cov neeg siv khoom.
