Abstract

Following our previous investigations on aqueous solutions of hypooxidized and iperoxidized species, we managed, by lowering the temperature of the solutions to 0 °C, to obtain, by electrochemical methods, Yb(II) and Yb(III) mixtures, enough stable to determine by a potentiometric method the formal redox potential of the Yb(III, II) couple. Its value, in a large range of total Ytterbium concentration, is − 1233 ± 3 mV against the molal hydrogen electrode in the 3.22 m NaCl medium.
