Dab tsi yog cov qauv ntawm electrode muaj peev xwm
Cov hluav taws xob electrode muaj peev xwm qhia tau qhov nyiam ntawm qee yam ion lossis atom kom tau txais hluav taws xob thiab raug txo kom tsawg. Yog tias cov hlau muab tso rau hauv nws cov kev daws teeb meem (kev sib xyaw ntawm cov hlau ions hauv kev daws tau hais raws li 1M), qhov sib txawv ntawm cov hlau hluav taws xob thiab cov qauv siv hluav taws xob hydrogen (qhov hluav taws xob muaj peev xwm raug xaiv ua xoom) ntawm 25 ° C yog hu ua cov hlau Tus qauv electrode muaj peev xwm.
