Effect of non-volatile solute on the freezing point of malonic acid

Abstract

The mixture of malonic acid and potassium chloride were obtained in various proportions. The freezing point of pure malonic acid was obtained in the range 134 and 135oC which is in agreement with the literature value of 135 OC. the freezing point of all the mixtures were below the literature value of 135 OC. the freezing point depression was found to be directly proportional to the amount of potassium chloride in the mixture.

Key word: malonic acid, potassium chloride, freezing point depression.
