Solubilities and solvation of aluminum(III), iron(III), and indium(III) 8-hydroxyquinolinates in methanol/water mixtures.

Solubilities are reported for aluminum, indium, and iron(III) complexes of 8-hydroxyquinoline and its 5-nitro, 5-sulfonato, and 7-iodo-5-sulfonato derivatives in water, methanol, and water/methanol mixtures, at 298.2 K. Transfer chemical potentials for the respective complexes have been derived from these data, and their trends are discussed in terms of solvation of the complexes by water and methanol.
