Pour the low plummet milk and soy milk into their several(prenominal) beakers. In the practice through beaker, mix 13g of powdery milk into 87 ml of inviolable water. Place the 3 beakers on a hot plate, and diddle the temperature of the crystallizationlinenesss in the beakers to 55 degrees C. check the temperatures with a thermometer. cast up drops of acetic acid until the liquid turns colorless. issue 4g of calcium carbonate to the remain clear liquid in each(prenominal) beaker. displace for a few legal proceeding with a stirring rod. The rest proteins leave precipitate.

Filter the solutions into their respective container and continue heating until alone 25 ml of solutions is left. Add 100ml of ethanol to the 25ml of solution in each container, and allow cooing. As the solution cools, lactose crystals will fake in each container. Collect there crystals and bank bill their weights with the digital weight scale. The entropy collected told us that the low fat milk has 528mg, powdered has 569mg and soy milk had 189mg. the milk with the least(prenominal) mass in crystal form was soy milk.
