【Abstract】 The 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,Δ_sH^∞_m,and Pitzer′s parameters β⁰L_MX and β¹L_MX were obtained.Then the values of apparent relative molar enthalpy Φ_L,hydration heat and relative partial molar enthalpy of solute（InCl₃）, 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.更多还原
