WebSupercooling, also known as undercooling, is the process of lowering the temperature of a liquid below its freezing point without it becoming a solid. It achieves this in the absence of a seed crystal or nucleus around which a crystal structure can form. The supercooling of water can be achieved without any special techniques other than chemical … WebThe freezing point depression constant for water is 1.86 °C • kg • mol-¹ and the density of water is 0.9978 g/mL. The pKa of acetic acid is 4.76, the molar mass is 60.052 g/mol and the density is 1.05 g/mL. You make an ideal solution of acetic acid in 945.9 g of water. The freezing point of this solution is -0.27 °C.
