Solubility of Tris(ethylenediamine)chromium(III) and Hexaureachromium(III) Hexacyanoferrates(III) in Water and Mixed Water-Organic Solvents

Abstract

The solubilities of tris(ethylenediamine)chromium(III) and hexa(urea)chromium(III) hexacyanoferrates(III) in aqueous solutions of different supporting electrolytes as well as in binary mixtures of water with methanol, tert-butyl alcohol and acetonitrile were measured at 25 °C. The experimental data have been used to evaluate the activity coefficients of the saturating salts in water and their Gibbs energies of transfer from water into the binary mixtures investigated.
