Abstract

Enthalpy of dilution measurements were made for NdCl3(aq) over the molality range 0.0080 mol.kg-1 to 2.6883 mol.kg-1 at temperatures from 297.89 K to 372.08 K and at a fixed pressure of 0.5 MPa. Published values of the osmotic coefficients, emfs of a reversible electrochemical cell, enthalpies of dilution, apparent molar heat capacities, and apparent molar volumes of NdCl3(aq) were critically assessed, and the more reliable of these results were combined with the present enthalpies of dilution to yield the parameters of an exended form of Pitzer's ion-interaction model valid to high molalities and for the temperature range 280 K to 375 K.
