Abstract
Solubility relations in the ternary system KCl-FeCl2-H2O have been determined by means of the visual polythermal method at 1 atm from 18 to 75??C along 10 composition lines. Solubilities of sylvite were measured along five composition lines defined by mixing KCl with five aqueous FeCl2 solutions containing 10, 20, 30, 38, and 45 wt % of FeCl2, respectively. Solubilities of FeCl2??4H2O were also determined along five composition lines defined by mixing FeCl2??4H2O with five aqueous KCl solutions containing 5, 10, 14.98, 19.97, and 24.99 wt % KCl, respectively. The maximum uncertainties in these measurements are ??0.02 wt % in KCl, ??0.15 wt % in FeCl2, and ??0.15??C. The data along each composition line were regressed to a smooth curve. The maximum deviations of the measured solubilities from the smoothed curves are 0.22 wt % in KCl and 0.12 wt % in FeCl2. Isothermal solubilities of sylvite and FeCl2??4H2O were calculated from these smoothed curves at 25, 40, 50, 60, 70, and 75??C.
