The solubility of tris(ethylenediamine)cobalt(III) hexacyanoferrate(III) were measured in aqueous solution of NaClO4, NaCl, KCl, KBr, K2SO4, Mg2SO4, (CH3)4NBr, (C2H5)4NBr, (1-C3H7)4NBr, and (1-C4H9)4NBr, as well as in the solution of NaClO4 in mixtures of water with methanol and tert-butyl alcohol. The experimental mean activity coefficients are compared with theoretical ones evaluated with the aid of extended Debye-Huckel relation. From the solubilities in water and in water-alcoholic solvents the thermodynamic transfer functions of the saturating salt were calculated.
