摘要：

Osmotic coefficients of aqueous solutions of La(ClO4)3, Pr(ClO4)3, Nd(ClO4)3, Sm(ClO4)3, Gd(ClO4)3, Dy(ClO4)3, Ho(ClO4)3, Er(ClO4)3, Tm(ClO4)3, Yb(ClO4)3, Lu(ClO4)3, Nd(NO3)3, Sm(NO3)3, and Gd(NO3)3 in the molality range from 0.1 mol kg-1 nearly to saturation at 298.15 K have been determined by the isopiestic method. The results obtained agree very well with those of Rard et al. published recently. A distinct two-series effect has been observed for the constant-molality values of rare-earth perchlorates. The results are discussed in terms of hydration of the cations and ionic association. © 1979.
