Freezing points for the system KCl–H2O are determined to 0.1° and 0.1% concentration over a range of concentrations including the eutectic. The solubility of potassium chloride in water at 25.22 °C. is measured. The heat capacities of a few rapidly and slowly frozen aqueous solutions of potassium chloride are investigated. The heat capacities of an approximately eutectic aqueous solution of potassium chloride are studied.Supercooling of aqueous solutions of potassium chloride is observed to be a constant factor under fixed cooling conditions, and its magnitude depends on the concentration of the solution. Aqueous solutions of potassium chloride, cooled rapidly to temperatures below the eutectic, are found to have approximately the same heat capacity values as those cooled slowly to the same temperatures. The heat of solution of potassium chloride at −10.7 °C. to form the eutectic concentration is calculated, and the relation between the phase rule diagram and heat capacities is discussed.
