Abstract

Intradiffusion coefficients of all species (cation, anion and solvent) and viscosities have been measured for aqueous solutions of gallium perchlorate in the concentration range 0-2.3 mol-kg-1 at 25°C. The perchlorate ion intradiffusion measurements were made using36ClO4- as the tracer species in diaphragm cell experiments. The development of a method to synthesize36ClO4- from36Cl- by electrolysis is described. The perchlorate intradiffusion coefficients results show a concentration dependence that is very similar to that for D(Cl-) in corresponding trivalent metal chloride solutions. A simple hydration analysis based on all the transport results estimates a total (effective) cation hydration for gallium within a 0-2 mol-kg-1 range of 10 (±1.5). © 1993 Plenum Publishing Corporation.
