Copper iodate, solubility

When the potential is scanned toward more positive values (Figure 9.8), it is possible to see the oxidation of atomic iodine to soluble iodine peaking at 0.95 V. Moreover, when the potential scan is extended toward more positive values, it is possible to see a large and broad anodic peak (not shown) corresponding to the formation of soluble iodate species. In the case of having lower amounts of specifically adsorbed anions, the reversible couple due to copper electroadsorption/desorption is slightly distorted. In fact, a new system has to be proposed as a consequence of the interaction between the anion and the metallic species.
