E.M.F. studies of electrolytic dissociation. Part 9.—Ytterbium acetate, malonate and sulphate in water at 25°C

Abstract

H₂-AgCl, glass-calomel and glass-AgCI electrode cells have been tested to estimate the dissociation constants at zero ionic strength of several ytterbium ion-pairs. The cells were designed so stock solutions could be added and the standard electrode potentials evaluated from the dissociation constants of the ion-pairing acids. Intercomparisons indicate that the uncertainties in the primary dissociation constants of YbAc²⁺, YbMal⁺ and YbSO⁺₄ are about ±5%.
