IDEAL POLARIZED (POLARIZABLE) ELECTRODE

"An electrode is called ""ideal polarizable"" if no electrode reactions can occur within a fairly wide electrode potential range. Consequently, the electrode behaves like a capacitor and only capacitive current ( no faradaic current) is flowing upon a change of potential. Many electrodes can behave as an ideal polarized electrode but only within an electrode potential range called the ""double-layer range."" Also called ""completely-polarizable electrode"" and ""totally-polarized electrode."" Contrast with ideal non-polarizable electrode. "
