The energy of hydration and solvation of indium salts in the acetylacetone-InCl3-water system

On the base of the previous papers concerning the investigations in the extraction systems the experiments were performed for the determination of thermodynamical distribution coefficient of indium salts between two phases in the system: acetylacetone-InCl3-water and the energy of hydration and solvation of that system. The results of the surface and interfacial potentials measurements of the system were presented as a function of the InCl3 concentration in the system before the extraction. The extraction coefficients of indium as a function of concentration of InCl3 in this system were determined. The method of the visible absorption spectra was used to the determination of concentration of indium in both phases after the extraction. The relation between the percentage of the extraction and the extraction coefficient was determined. The investigations were performed in the system containing 0.1 M HCl and 0.001 M HCl in the aqueous phase. The results of experiments are tabulated and graphically presented in figures. (author)
