| Abstract: | he 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. |
