Multicomponent Solutions

A method is described by which univariant composition data for multicomponent solutions may be tested for consistency or accuracy, and used to estimate or verify invariant points, by reference to the vapor pressure data for an appropriate binary subsolution derived from the system. A subsolution is defined as any homogeneous part of a multicomponent solution, such that it is composed of a smaller number of the components than the total but in which the relative masses of these components are the same as in the parent solution.Published data for ternary systems containing sulfuric acid, water, and the metal sulfates MnSO4, FeSO4, ZnSO4, BeSO4, Na2SO4, and CuSO4 are examined. Some new data for the CuSO4 system are also presented. The subsolution in each case is the binary H2SO4–H2O solution, for which adequate vapor pressure data are available.

Raman spectra of (M, M')F–AlF3 (M, M' =Li, Na, K) molten salts have been obtained at 1293 K. The intensity ratios between the bands that are characteristic of the different complexes are strongly affected by the ratio M/M', especially when one of the alkaline cations is Li+. Its presence together with another cation seems to produce an increase in the acidity of the melt. The result of the deconvolution of the spectra compares well with vapor pressure data from the literature, showing the same kind of deviation. A qualitative explanation is proposed, but a quantitative modeling has not been possible up to now, because there is a lack of thermodynamic data that would allow a comparison with the spectroscopic results.
