WebRedoxpotential (reduktion-oxidation potential) är en elektrisk potential (mätt i volt) som mäter en substans affinitet per elektroner (det vill säga energi som frigörs när föreningen bildas eller splittras dividerat per elektron). Om ett ämne oxideras så finns ett ämne som också reduceras, och vice versa, därav namnet.. Man utgår vanligtvis från väte, som har …
