摘要	The molar enthalpies of solution of VOSO4 center dot 3.52H(2)O( s) at various molalities in water and in aqueous sulfuric acid (0.1 mol.kg(-1)), Delta H-sol(m), were measured by a solution-reaction isoperibol calorimeter at 298.15 +/- 0.01 K. An improved Archer's method to estimate the standard molar enthalpy of solution, Delta H-sol(m)0, was put forward. In terms of the improved method, the values of Delta H-sol(m)0 =- 24.12 +/- 0.03 kJ . mol(-1) of VOSO4 +/- 3.52H(2)O(s) in water and Delta H-sol(m)0 = - 15.38 +/- 0.06 kJ . mol(-1) in aqueous sulfuric acid were obtained, respectively. The data indicates that the energy state of VOSO4 in aqueous H2SO4 is higher than that in pure water.
