Abstract
WHEN nitrate solutions are employed as the catholyte in an electrolytic cell, with the electrodes separated by an anion-permeable ion-exchange membrane, many metallic hydroxides tend to precipitate in the cathode compartment, to compensate for the loss of nitrate ions to the anolyte. For a trivalent cation, the overall reaction can be represented as follows:
