Popis: The standard molar enthalpies of solution of cerium and lanthanum silicates (β-Ce2Si2O7and β-La2Si2O7) in (6.20 mol·dm-3HCl + 0.147 mol·dm−3HF) (aq) were measured. From these values the standard molar enthalpies of formation have been deduced: ΔfHmo(Ce2Si2O7,cr, β, 298.15 K) = −(3807.6 ± 4.5) kJ·mol−1and ΔfHmo(La2Si2O7, = −(3815.7 ± 4.5) kJ·mol−1.
