FORMATION of hydroxy ions according to reactions such as Cu++ + H2O = CuOH+ + H+ (A) has been well-established for cupric salts (4), ferric salts (6), and others. Reactions of such hydroxy ions with the cation exchange charges of montmorillonite were postulated (2) to explain the excess of exchange sorption over the stoichemetric amounts expected of multivalent ions. By reaction A, two milliequivalents of copper occupy only one milliequivalent of the base exchange capacity. The reaction is also characterized by the formation of hydrogen ion.
