Mercury(II) oxide and silver(I) oxide electrodes in aqueous solutions (Technical Report)

Abstract

The standard aqueous potentials of the mercury(II) oxide electrode and of the silver(I) oxide electrode covering the temperature range from 283 to 318 K have been critically analysed (with special attention to the standard states implied) and redetermined: as a result, recommended values are tabulated for both the respective ≪acid≫ and ≪basic≫ standard potentials. From these potentials, accurate values for the standard solubility products of the corresponding hydroxides, Hg(OH)2 and AgOH, have been also derived. The usefulness and applications of the mercury(II) oxide electrode, as well as the limited applicability of the silver(I) oxide electrode, are described. © 1994, Walter de Gruyter.
