Study on the capacities,heats of dilution and properties of concentrated potassium carnallite solutions at 298.15 K

The heats of dilution of the infinitesimally dilute potassium carnallite solutions at 298.15 K have been studied by continuous titration from 1.8942 to 0.01044 mol·kg^?1, and an equation for the curve of heats of dilution has been fitted. It was shown that the enthalpy of dilution for the same concentration of the carnallite solution is equal to the sum of those of KCl and MgCl₂ solutions. The equation for the curve of enthalpy of dilution corresponds to that of natural carnallite.
