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, Δ_sH^∞_m , and Pitzer′s parameters β^(0)L_MX and β^(1)L_MX 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 InCl₃with 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.

Key words: Keywords Solution enthalpy; Pitzer′s theory; Isoperibol calorimeter; Electrolyte solution; InCl₃; Hydration heat of ion
