Thaum ib qho ion mus txog lub electrode lawv poob lossis nce ib qho hluav taws xob nyob ntawm lawv cov nqi. Tsis zoo them ions poob electrons los ua nruab nrab atoms Positively charged ions tsim nruab nrab atoms ntawm tau txais electrons. Tau txais electrons yog hu ua txo. Poob electrons hu ua oxidation.
Yuav ua li cas rau ions ntawm electrodes?
Cov ions raug them zoo txav mus rau qhov tsis zoo electrode thaum electrolysis. Lawv tau txais electrons thiab raug txo. Tsis zoo them ions txav mus rau qhov zoo electrode thaum electrolysis. Lawv plam electrons thiab oxidized.
Qhov twg electrode ua tsis zoo ions txav mus rau?
Electrodes thiab ions
Cov electrode tsis zoo hauv electrolysis hu ua the cathode. Kev them nyiaj zoo ions txav mus rau cathode. Qhov zoo electrode hauv electrolysis hu ua anode. Tsis zoo them ions txav mus rau lub anode.
Qhov twg electrode ua ions nce electrons?
Lawv tsuas yog muab qhov chaw rau ions kom nce lossis poob electrons kom lawv tsim cov khoom. Graphite (ib daim ntawv ntawm carbon) thiab platinum feem ntau yog siv los ua inert electrodes. Cov hlau zoo ions tau nyiam rau qhov tsis zoo electrode, qhov twg lawv tau txais electrons thiab tsim hlau atoms.
Yuav ua li cas ntawm cov electrodes?
Thaum ions ncav cuag ib qho hluav taws xob, lawv nce lossis poob electrons. Yog li ntawd, lawv tsim atoms lossis molecules ntawm cov ntsiab lus: tsis zooions poob electrons ntawm qhov zoo them anode.
