Cov yooj yim cell los yog voltaic cell muaj ob lub electrodes, ib qho ntawm tooj liab thiab lwm yam ntawm zinc dipped nyob rau hauv ib tug tov ntawm dilute sulfuric acid nyob rau hauv ib lub iav raj. Thaum txuas ob lub electrodes sab nraud, nrog ib daim hlau, tam sim no ntws los ntawm tooj liab mus rau zinc sab nraum lub cell thiab los ntawm zinc rau tooj liab hauv nws.

Ua li no, yuav ua li cas thiaj ua tau ib lub xov tooj yooj yim?

A yooj yim cell tau ua ua los ntawm kev sib txuas ob yam hlau sib txuas nrog ib qho electrolyte. Ib tug naj npawb ntawm hlwb tau txuas rau hauv series ua ib lub roj teeb, uas muaj qhov voltage siab dua ib zaug cell . Hauv tsis-rechargeable hlwb , np. alkaline hlwb , ib qho hluav taws xob raug tsim kom txog thaum ib qho ntawm cov reactants siv.

voltaic cell ua haujlwm li cas? Ua haujlwm Cov ntsiab lus hluav taws xob tam sim no yog kev txav ntawm cov khoom siv hluav taws xob, hluav taws xob lossis ions, los ntawm tus neeg xyuas pib. A voltaic cell yog ib qho electrochemical cell uas siv tshuaj tiv thaiv los tsim hluav taws xob hluav taws xob. Cov oxidation thiab txo cov tshuaj tiv thaiv yog muab cais rau hauv compartments hu ua ib nrab- hlwb.

Qhov yooj yim voltaic cell yog dab tsi?

A yooj yim voltaic cell muaj ob daim hlau ntawm cov hlau sib txawv rau hauv ib qho electrolyte. Nyob rau hauv qhov zoo davhlau ya nyob twg, cov electrons yuav raug tso tawm mus rau qhov zoo ions nyob rau hauv lub electrolyte. Hauv ib voltaic cell , qhov tsis zoo davhlau ya nyob twg yog lub anode thaum lub zoo davhlau ya nyob twg yog lub cathode.

Lub tshuab hluav taws xob hluav taws xob ua haujlwm li cas?

Ib electrochemical cell tuaj yeem tsim los ntawm kev tso cov hlau electrodes rau hauv cov electrolyte qhov twg cov tshuaj tiv thaiv yog siv los yog tsim hluav taws xob tam sim no. Electrochemical hlwb uas tsim hluav taws xob tam sim no hu ua voltaic cell los yog galvanic hlwb , thiab cov roj teeb uas muaj xws li ib lossis ntau dua li hlwb.
