- Abstract
The aqueous solutions of mineral-like compounds MHSiUO6 · nH2O (M = Li, Na, K) at 298 K were studied. A quantitative model of a crystalline uranosilicate-aqueous solution system was derived from the solubility data and was used to calculate the solubility products and Gibbs formation functions of these compounds. The Gibbs energies of formation of silicic acid and other ionic and molecular Si(IV) species in solution were also calculated. The solubility of uranosilicates in aqueous solutions outside the experimentally studied range was predicted.
