Description

The enthalpy of reaction between praseodymium metal and 1.07 n HCl and the enthalpy of solution of praseodymium trichloride in 1.07 n HCl and water were measured in a swinging isothermal-shell hermetic calorimeter at 298.15 K. The results were used to calculate the enthalpy of formation of the praseodymium ion in the state of an infinitely dilute aqueous solution, ΔfH0298.15 Pr3+(sln, ∞ H2O) = -687.8 ± 1.7 kJ/mol

Abstract (Russian)

В герметичном качающемся калориметре с изотермической оболочкой при 298.15 К измерены энтальпия реакции металлического празеодима с 1.07 н. НСl и энтальпии растворения трихлорида празеодима в 1.07 н. НСl и воде. По полученным данным рассчитана энтальпия образования иона празеодима в состоянии бесконечно разбавленного водного раствора: ΔfН0298.15 Pr3+ (р-р, ∞ H2O) = -687.8 ±1.7 кДж/моль
