This work presents solubility data for rare earth metal bromides in water and in aqueous ternary systems. Compilations of all available experimental data are introduced for each rare earth metal bromide with a corresponding critical evaluation. Every such evaluation contains a collection of all solubility results in water, a selection of suggested solubility data and a brief discussion of the multicomponent systems. Because the ternary systems were almost never studied more than once, no critical evaluations of such data were possible. Only simple bromides (no complexes) are treated as the input substances in this work. The literature has been covered through the end of 2011.

The evaluators and compilers gratefully acknowledge the encouraging help of the IUPAC Commission V.8 and later Subcommittee on Solubility and Equilibrium Data. The project was initiated in the early 1980s by Mioduski during the catalytic chairmanship of A. S. Kertes and continued during the chairmanships of J. W. Lorimer, M. Salomon, D. Shaw, H. Gamsjäger, D. Knox, and C. Magalhães. Advice and suggestions of Salomon and Lorimer during preparation of the paper were very fruitful. The sudden death of Mioduski in 2000 stopped the project for several years. In 2004, Gumiński started to complete the literature from the past three decades, supplement and rearrange the critical evaluations and data sheets, check numerical data, and retype the whole material into electronic form. Realization of the final stage of the volume preparation was made possible by inclusion of D. Zeng into the project, who found many papers in Chinese, translated them, calculated solubility equations, and improved the Critical Evaluations. Therefore, Gumiński is very thankful to Gamsjäger and W. Voigt for the successful involvement of Zeng in the undertaking. The authors of this volume also acknowledge the important inputs of H. U. Borgstedt, J. Burgess, Y. Sh. Chen, K. A. Gschneider, J. Kijowski, K. L. Loening, H. Miyamoto, J. A. Rard, M. Sripkin, Z. X. Tang, V. Valyashko, and Y. L. Xu, who provided the authors with reprints of hardly available journal papers and reports.
C.G. is thankful for financial support to the BST and IUPAC projects.
