| 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 using36ClO

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). |
