【Abstract】 The solution heats of Nd(NO3)3 · nH2O(n = 6,4) and Sm(NO3)3· mH2O(m = 6,5) in water have been measured by digital compensation calorimeter at 298.15K. The values are 18.859±0.028,10.301±0.082,19.283±0.913,and 10.642±0.096 kJ / mol, respectively. The standard formation heats, dehydration enthalpies and lattice energies of the hydrates are reported.更多还原
