• The dissolved state of ions in solution was investigated through the study of separation mechanism of a series of tervalent hexammine-type cobalt(III) complexes in thin-layer chromatography and in electrophoresis. The results obtained are summarized as follows. In the case of strongly hydrated complexes, a strongly hydrated anion has a greater tendency towards association than a weakly hydrated anion. On the contrary, in the weakly hydrated complexes, a weakly hydrated anion is associated more easily than a strongly hydrated anion. From these findings, ionic association was presumed to occur through direct contact of a complex cation and an anion.
