Foil, wire or disc electrode made of gold which is easily fabricated into a variety of electrode geometries.
Note: At positive potentials, \(\ce{Au}\) forms an oxide and/or chemisorbed oxygen layer, while in the presence of complexing anions, such as chloride or cyanide, it readily undergoes oxidation and dissolution, limiting its working potential range and its applications.
