| 英文摘要 | low-temperature heat capacities of the complex zn(thr)so4.h2o (s) have been precisely measured with a small sample adiabatic calorimeter over the temperature range from 78 to 373 k. the initial dehydration temperature of the complex (t-d = 325.50 k) has been obtained by analysis of the heat-capacity curve. the experimental values of molar heat capacities have been fitted to a polynomial equation by least square method. the standard molar enthalpy of formation of the complex has been determined from the enthalpies of dissolution (delta(d)h(m)(theta)) of [znso4.7h(2)o(s)+thr (s)] and zn(thr)so4.h2o (s) in 100 ml of 2 mol dm(-3) hcl solvent as: delta(f)h(m,zn(thr)so4.h2o)(theta) = -2111.7 +/- 3.4 kj mol(-1). these experiments were made by using an isoperibol solution calorimeter at 298.15 k.
