Thermodynamic characterization of the amphoterism of hydroxides and oxides of scandium subgroup elements in aqueous media

Effect of the pH value on the molar solubility of solid hydroxides M(OH)(3) and oxides M(2)O(3) at 25A degrees C and the constants of acid-base equilibria in aqueous media for crystalline hydroxides and oxides and dissolved hydroxides M(OH)(3) (M = Sc, Y, La) were calculated using the thermodynamic method, with the formation of hydroxo complexes taken into account.
