Claim: The working electrode is the electrode in an electrochemical system that has five special types. Ultramicroelectrode (UME), Rotating disk electrode (RDE), Rotating ring-disk electrode (RRDE), Hanging mercury drop electrode (HMDE) and Dropping mercury electrode (DME) that can be used in conjunction with a three electrode system.
Evidence: The working electrode is the electrode in an electrochemical system on which the reaction of interest is occurring. Ultramicroelectrode (UME) Rotating disk electrode (RDE) Rotating ring-disk electrode (RRDE) Hanging mercury drop electrode (HMDE) Dropping mercury electrode (DME) The working electrode is often used in conjunction with an auxiliary electrode, and a reference electrode in a three electrode system.
