| Abstract: | The heats of dilution and heat capacities of system Li2SO4-K2SO4-MgSO4-H2O and subsystems Li2SO4-K2SO4-H2O, Li2SO4-MgSO4-H2O and K2SO4-MgSO4-H2O were measured to cover ionic strength range from 15 to 0.1 at 298.15K. The data of the heat of dilution were extrapolated to infinite dilution by use of the Debye-Huckel liminting law to obtain relative apparent molal enthalpies over the ionic strength range 15-0.0001. |
