The Relationship

Although great advances have been made during the last thirty years in our knowledge of dilute solutions, there has been no corresponding advance in respect of concentrated solutions. This is primarily due to the fact that hitherto no simple and general relationship has been discovered between the conductivity and the concentration of concentrated solutions of electrolytes. Ostwald's law of dilution holds only for dilute solutions of weak electrolytes, and the formulæ of Rudolphi and Van T'Hoff are applicable only to dilute solutions of good electrolytes. It seems therefore important to inquire whether the difficulty may not be to some extent overcome by an alteration in the mode of representing the facts.

[Co(en)2SCH2CH2NH2]2+ ion is oxidized to [Co(en)2SOCH2CH2NH2]2+ by the oxo-monoperoxovanadium(V) complexes in aqueous media. These reactions are accompanied by oxygen atom transfer from the peroxo ligand to the coordinated sulfur atom. The relative reactivities for each substrate stand in the order: [VO(O2)(ada)]- << [VO(O2)nta]2- ~ H2O2 ~ [VO(O2)(H2O)4]+ < [VO(O2)(quin)2]3- << [VO(O2)(H2O)2(pic)], where ada = N-(carbamoylmethyl)iminodiacetato(2-), nta = nitrilotriacetato(3-), quin = 2,3-pyridinedicarboxylato(2-) and pic = 2-pyridinecarboxylato(1-) ligands. The effect of pH on the second order rate constant for oxidation by monoperoxo-nta complex is in the pH range 4.8-6.5 consistent with equation k(298.2 K) = 0.709 + 1.28 . 105 [H+]. Two new oxo-monoperoxo complexes of vanadium(V), NH4[VO(O2)(ada)] . H2O and (NH4)3[VO(O2)(quin)2] . 3 H2O, were synthesized and characterized. The salt effects on the thiolatocobalt(III) oxidation by vanadium(V) oxo-monoperoxo complexes as well as by H2O2 were studied at 298.2 K in different, up to 5 M solutions of electrolytes. The results can be rationalized in terms of the salt-water interactions.

Solubility Isotherms

Computational analysis of solubility isotherms in ternary systems consisting of water and two solutes having a common ion was suggested and the respective software was developed. This hydration analysis was applied to model systems NH4CNS - NaCNS - H2O at 5, 25 and 50 °C and NaX - KX - H2O (X = Cl, Br, I) at 25 °C. The results obtained are discussed and the way in which the hydration analysis gives information on ionic processes in saturated electrolyte solutions is demonstrated.
