Popis:	The standard enthalpies of formation of anhydrous 3d transition metal uranyl sulfates and their pentahydrates at 298.15 K were determined by reaction calorimetry. The heat capacities of the compounds AIIUO2(SO4)2·5H2O (AII = Mn, Fe, Co, Ni, Cu, Zn) and CuUO2(SO4)2 at 7– 300 K were determined by adiabatic vacuum calorimetry, and the thermodynamic functions of these compounds were calculated. The standard entropies and Gibbs energies of formation of these compounds at 298.15 K were determined. The thermodynamics of dehydration of AIIUO2(SO4)2·5H2O and of the precipitate-solution equilibria involving these compounds were studied.
