In the paper the relation of modern concepts on solutions with colligative solution properties is fully formalized. The necessity of obvious taking into account not only the well-known Vant-Hoff’s principle about universal behavior of matter in the dissipated state, but the specificity of detailed components in comparison with initial (brutto-) components. The aggregate of consequences from Gibbs fundamental equation is supplemented by means of these grounds. 相似文献

The literature data on the equilibrium constants of formation of HgCl–
3 solv and HgCl2–
4 solv from HgCl2 solv and Cl–
solv in aqueous perchlorate–chloride solutions were generalized. The individual electronic absorption spectrum of the trichloro complex of mercury(II) was obtained for the first time, and the effect of the ionic strength on the spectra of di-, tri-, and tetrachloro complexes of mercury(II) was considered. The previously developed procedures for the resolution of absorption spectra into individual bands were found to be suitable for interpretation of spectral changes experimentally observed for solutions as the result of stepwise complexation. The parameters of the absorption bands in the spectra of chloro complexes of mercury(II) were determined. 相似文献

The strontium sulfate solubility has been studied in mixtures of isomolar MCl and HCl solutions (M = Li, Na, K, Cs) with ionic strengths of I = 0.5, 1.0, 2.0, 3.0, and 4.0 at 25°C. At I ≥ 2, the SrSO4 solubility as a function of hydrogen ion concentration passes through a maximum in all systems but (Li,H)Cl. The position of this maximum depends only slightly on the nature and ionic strength of the medium. The presence of the maximum is unambiguous evidence that there are secondary effects of the medium associated with the substitution of H+ for M+. These effects oppose the ordinary shift of the HSO 4 ? formation equilibria. A method is suggested for separating these effects. The standard values of pSP0 and logβ0, determined by extrapolation to zero ionic strength, are in satisfactory agreement with the literature. The parameter α1, which characterizes the secondary effects of the medium on one of the basic equilibrium constants (log K S1 O ), increases in the order (Li,H)Cl < (Na,H)Cl < (K,H)Cl < (Cs,H)Cl. 相似文献
