You'll also need to select those that allow you to observe the salt and sugar as it dissolves. Explanation: Whenever you freeze a dilute aqueous sugar solution pure water freezes first, departing a far more concentrated solution before you achieve a higher power of sugar known as the eutectic concentration. Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. 20 Why does ice melt faster in freshwater than salt water?
