| 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. |
