N2 - The aim of this study is the synthesis of CuSeO3 center dot 2H(2)O (chalcomenite analog), ZnSeO3 center dot 2H(2)O, and ZnSeO3 center dot H2O and the investigation of their solubility in water. CuSeO3 center dot 2H(2)O has been synthesized from solutions of Cu nitrate and Na selenite, while Zn selenites were synthesized from solutions of Zn nitrate and Na selenite. The samples obtained have been examined with X-ray diffraction and infrared and Raman spectroscopy. The solubility has been determined using the isothermal saturation method in ampoules at 25 degrees C. The solubility has been calculated using the Geochemist's Workbench (GMB 9.0) software package. Solubility products have been calculated for CuSeO3 center dot 2H(2)O (10(-10.63)), ZnSeO3 center dot 2H(2)O (10(-8.35)), and ZnSeO3 center dot H2O (10(-7.96)). The database used comprises thermodynamic characteristics of 46 elements, 47 base particles, 48 redox pairs, 551 particles in solution, and 624 solid phases. The Eh-pH diagrams of the Zn-Se-H2O an
