Ib qho electrode uas tsis muaj lus teb rau kev ua haujlwm ntawm hydrogen ions hauv kev daws teeb meem thiab muaj peev xwm paub thiab tsis tu ncua electrode yog hu ua siv electrode.
Lub luag haujlwm tseem ceeb ntawm kev siv hluav taws xob yog ntsuas lub zog hluav taws xob ntawm lub roj teeb thiab lub ntsuas ntsuas rau kev suav cov peev txheej electrode. (Faj seeb: lub electrode ntsuas los ntawm Bai yog hu ua cov electrode ua hauj lwm, thiab cov electrode opposite rau cov ua hauj lwm electrode yog hu ua lub auxiliary electrode.)
Cov electrodes muaj xws li mercurous sulfate electrode, calomel electrode thiab nyiaj / nyiaj chloride electrode. Feem ntau siv yog calomel electrode thiab nyiaj / nyiaj chloride.
Lub luag haujlwm hauv kev ntsuas roj teeb yog los muab thiab tswj kom muaj peev xwm siv tau ruaj khov. Yog li, qhov yuav tsum tau ua rau cov khoom siv electrode yog qhov muaj peev xwm ruaj khov thiab tseem ceeb, qhov kub coefficient yog me me, thiab qhov polarization muaj peev xwm me me thaum muaj tam sim no. Feem ntau siv siv electrode muag hauv khw yog 232 siv electrode.
