Abstract:

AbstractThe molar solution enthalpies of scattered metal compound InCl3  with various molalities were determined at 298.150 K in water by the solution reaction isoperibol calorimeter.  According to Pitzer′s electrolyte solution theory,  the molar solution enthalpy of InCl3  at infinite dilution,  ΔsH∞m ,  and Pitzer′s parameters  β(0)LMX and   β(1)LMX were obtained.  Then the values of apparent relative molar enthalpy ΦL,  hydration heat and relative partial molar enthalpy of solute(InCl 3),  L2,  were calculated,  respectively.  At last,  the interaction of InCl3 with water was discussed.  In terms of the crystal lattice energy of InCl3 and the hydration heat of Cl-,  the values of the hydration heat of InCl3 and In3+ were obtained.
