| Abstract | IT WAS SHOWN THAT DURING ELECTROCHEMICAL OXIDATION OF COPPER IN SOLUTIONS OF BARIUM HYDROXIDE OR IN NAOH SOLUTIONS CONTAINING BA(OH)2 A COMPOUND OF TRIVALENT COPPER OR TYPE BA(CUO2)2 IS FORMED. THE FORMATION OF INSOLUBLE BARIUM CUPRATE DEPENDS ON THE CONCENTRATION OF HYDROXYL IONS AND BARIUM IONS. WITH SUFFICIENTLY HIGH CONCENTRATIONS OF THESE IONS, THE YIELD FOR CU(3) IS THE MAXIMUM. BASED ON THE FINDINGS IT IS HYPOTHESIZED THAT AN EXTREMELY UNSTABLE TRIVALENT COPPER OXIDE OR HYDROXIDE IS INITIALLY FORMED AT THE ANODE, WHICH IS STABILIZED BY THE HYDROXYL IONS AND BARIUM IONS CONTAINED IN THE SOLUTION. BARIUM CUPRATE CAN ALSO BE PRODUCED BY EXCHANGE REACTION OF BARIUM IONS WITH ELECTROCHEMICALLY SYNTHESIZED SODIUM CUPRATE. |
