| Abstract: | The heats of dilution and heat capacitics of MgB4O7-MgSO4-MgCl2-H2O quaternary system and MgB4O7-MgSO4-H2O and MgB4O7-MgCl2-H2O subsystems were measured in the tonic strength range from 19 to 0.1 at 298.15K. The data of the heat of dilution were extrapolated to infinite dilution by use of the Dcbye-Huckcl limiting law to obtain relative apparent molal enthalpies over the ionic strength I range from 19 to 0.0001. |
