"A class of electrode reactions involving oxidation/reduction of a solid metal and its dissolved ion. E.g., if a copper metal rod is immersed in a copper sulfate solution, the copper cations can be cathodically reduced to copper metal, or the copper metal can be anodically oxidized to copper ions. Compare with a redox reaction where both the oxidized and the reduced species are in solution. The terms ""electrodeposition"" and ""electrodissolution"" are often used to describe these reactions. These reactions are used in many technologies, such as electroplating, electrowinning, and electrorefining. And also in electrogravimetry. "
