Description
Enthalpies of solution of TiCl4(l) in aqueous perchloric acid have been measured in an isothermal calorimeter at T=298.15K at ionic strengths of (1.964, 3.002, and 4.062)mol.kg-1. These results were extrapolated to zero ionic strength using an extended Debye-Huckel equation, to yield the standard enthalpy of solution ΔslnHmo (T=298.15K)=-(268.03+/-0.45)kJ.mol-1; from which the standard partial molar enthalpy of formation of the titanyl ion was derived: ΔfHmo (TiO2+,aq,T=298.15K)=-(689.4+/-4.3)kJ.mol-1
