Enthalpy changes for the reaction of HCl(aq) with Na 2 WO 4 (aq) were measured at T = 298.15 K in a HT-1000 calorimeter. The standard enthalpy of reaction for the formation of W 7 O 6- 24 (aq) was calculated on the basis of the experimental results, r H o m (298.15 K) = -(320.7 ยฑ 1.0) kJ โข mol -1 .
The standard molar enthalpy of formation of the yttrium ion in aqueous solution at infinite dilution at T = 298.15 K was determined by two independent ways by solution calorimetry and was found to be -(733.51 ยฑ 2.07) kJ โข mol -1 . During the experiment, the molar enthalpies of reaction of metallic y
The molar enthalpies of solution of UTeO 5 , UTe 3 O 9 , TeO 2 , and UO 3 in HCl (aq, c = 11 mol โข dm -3 ) have been measured by using an isoperibol calorimeter. From these results and other auxiliary data, the standard molar enthalpies of formation f H o m (298.15 K) of UTeO 5 (cr) and UTe 3 O 9 (c
