Hydrate numbers of scandium sulfate as deduced from solubility data
Description
A simple method for determination of the hydrate numbers of saturating multi-hydrate salts in developed. The method demonstrated for scandium sulfate is based upon estimation of the enthalpy of solution of the hydrates from the solubility smoothing equations. It is shown that in the Sc2(SO4)3-H2O system, contrary to common opinion, the equilibrium solid phases are: Sc2(SO4)3*6H2O at 273-295 K, Sc2(SO4)3*5H2O at 295-333 K and Sc2(SO4)3*4H2O at 333-373 K. The solubility smoothing equations for the hexa-, penta- and tetrahydrate of scandium sulfate are given. (author) 13 refs.; 1 fig.; 2 tabs
