Abstract
The heats of dilution of the infinitesimally dilute potassium carnalli te solutions at 298.15 K have been studied by continuous titration fro m 1.8942 to 0.01044 mol . kg(-1), and an equation for the curve of hea ts of dilution has been fitted. It was shown that the enthalpy of dilu tion for the same concentration of the carnallite solution is equal to the sum of those of KCl and MgCl2 solutions. The equation for the cur ve of enthalpy of dilution corresponds to that of natural carnallite.
