A galvanic cell muaj ob ib nrab ntawm tes, xws li cov electrode ntawm ib nrab ntawm tes yog tsim los ntawm hlau A, thiab cov electrode ntawm lwm ib nrab ntawm tes yog tsim los ntawm hlau B; cov tshuaj tiv thaiv redox rau ob lub hlwb sib cais yog li no: An+ + ne− ⇌ A . Bm+ + me- ⇌ B.
Cov tshuaj tiv thaiv ntawm tes ntawm galvanic yog dab tsi?
Tus redox cov tshuaj tiv thaiv hauv galvanic cell tshwm sim tsuas yog ntawm qhov sib cuam tshuam ntawm txhua ib nrab ntawm tes cov tshuaj tiv thaiv sib xyaw thiab nws cov electrode. Txhawm rau kom cov reactants sib cais thaum tswj kev sib npaug, ob qhov kev daws teeb meem ib nrab ntawm tes tau txuas nrog lub raj uas muaj cov tshuaj inert electrolyte hu ua choj choj.
Qhov twg yog rau galvanic cell?
Electrons ntws anode rau cathode.
Yuav tsum tau dab tsi rau galvanic cell?
Teeb tsa ntawm Galvanic Cell
Lub xovtooj xav tau zoo suav nrog ob electrodes. Ib qho ntawm cov electrodes, lub cathode, yuav tsum yog ib qho zoo electrode thaum lwm qhov, yuav tsum yog lub anode, lub electrode tsis zoo. Ob lub electrodes no yuav tsum tsim ob yam tseem ceeb ntawm galvanic cell.
