A CONSISTENT APPROACH TO TABULATION OF EVALUATED SOLUBILITY DATA - APPLICATION TO THE BINARY-SYSTEMS RBCL-H2O AND UO2(NO3)2-H2O

Many scientific disciplines require accurate solubility data. However, the proliferation of published values from research over the past cen tury reveals a need for a consistent approach to tabulation and evalua tion of these data, along with recommended methods based on theory for interpolation and extrapolation. The approach used in the IUPAC Solub ility Data project is described, using as examples the binary systems RbCl-H2O and UO2(NO3)(2)-H2O. In this approach, all relevant solubilit y data are compiled and tabulated. The tabulated data are then evaluat ed using a systematic approach based upon thermodynamics. The results are tables of recommended values and fitting equations for solubilitie s and, in some cases, corresponding densities and vapor pressures.
