Abstract: Isopiestic measurements were made for the ternary systems H2O+La(NO3)3+Pr(NO3)3, H2O+La(NO3)3+Nd(NQ3)3 and H2O+Pr(NO3)3+Nd(NO3)3 and their binary sub-systems H2O+La(NO3)3, H2O+Pr(NO3)3 and H2O+Nd(NQ3)3 at T=298.15 K, taking NaCl(aq) and CaCl2(aq) as reference systems. The experimental results showed that their thermodynamic characteristics conform well with the partial ideal solution model and Zdanovskii's rule within the experimental error range, i.e. |Δ|&le0.0010.
