Yog vim li cas ob lub ntsiab ntawm ib tug galvanic cell sib cais los ntawm ib leeg? Cov hlau yog muab tso rau hauv ib nrab- hlwb uas txuas nrog tus choj ntsev. Kev txav ntawm electrons los ntawm anode mus rau cathode yog cov hluav taws xob tam sim no.

Ntawm no, vim li cas ob lub ntsiab lus ntawm lub cell sib cais los ntawm ib leeg?

Hauv galvanic cell muaj ob ib nrab- hlwb . Txhua ib nrab- cell muaj ib tug electrode nyob rau hauv ib tug electrolyte. Cov kev sib cais Nws yog ib qho tsim nyog los tiv thaiv cov tshuaj tiv thaiv ncaj qha ntawm oxidation thiab txo cov tshuaj tiv thaiv, tsim kom muaj qhov sib txawv.

Kuj Paub, galvanic hlwb siv rau dab tsi? Galvanic Cells . Ntawm lwm yam hlwb , a galvanic cell yog ib hom electrochemical cell. Nws yog siv muab hluav taws xob tam sim no los ntawm kev hloov cov electrons los ntawm cov tshuaj tiv thaiv redox. A galvanic cell yog lub tswv yim piv txwv ntawm yuav ua li cas lub zog tuaj yeem siv tau siv cov kev cuam tshuam yooj yim ntawm ob peb lub ntsiab lus.

Ib yam li ntawd, vim li cas thiaj muaj 2 ib nrab ntawm cov hlwb hauv ib lub cell electrochemical?

Electrochemical hlwb feem ntau muaj ob ib nrab - hlwb . Ib nrab - hlwb cais tus oxidation ib nrab - tshuaj tiv thaiv los ntawm tus txo ib nrab -reactions thiab ua rau nws muaj peev xwm rau tam sim no ntws los ntawm ib tug sab nraud hlau. Kev txo qis tshwm sim ntawm tus cathode. Ntxiv tus choj ntsev ua tiav tus Circuit Court cia tam sim no ntws.

Ob hom electrochemical hlwb yog dab tsi?

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.
