Energy … WebTo freeze the ice cream mixture, it is necessary to use “colder” ice. Again, properties of solutions provide the answers. A salt-ice mixture has a lower freezing point than pure ice, so it acts as “colder” ice. The more salt added to the ice, the lower the freezing point. The ice cream mixture can then lose more energy to
