摘要：

The heats of mixing aqueous solutions of magnesium chloride with the chlorides of lithium, sodium, potassium, and cesium at constant ionic strength have been measured at 25° and ionic strengths of 0.5 to 3.0. The magnitudes of the heats of mixing are similar to the magnitudes of the heats of mixing two alkali chlorides. At the lower concentrations RTh0 becomes more positive. A trend to plus infinity for RTh0 is expected from the limiting law. If the contributions of oppositely charged ions are estimated and subtracted from the heat of mixing, the sign of the remainder correlates reasonably well with the properties of the water structure around the two cations. This observation extends the correlation to charge-asymmetrical mixtures.
