9.12 Types of Electrodes. In an electrochemical cell, there are two electrodes, positive and negative. Each electrode constitutes a half cell or a single electrode. Although a number of electrodes are possible but the more important of these electrodes are grouped into the following types: (i) Metal-metal ion electrodes. (ii) Metal-metal insoluble salt electrodes.
