Carolina ChemKits®: Ice Cream and Freezing Point Depression
Teach freezing-point depression, a colligative property, and yield a delicious result. Students use sodium chloride to lower the freezing point of ice and freeze a single serving of nondairy instant creamer. Varying the amount of sodium chloride gives unexpected (but still tasty!) results. This activity covers the nature and real-life applications of colligative properties, freezing-point constant, and the van’t Hoff factor.
