Unformatted text preview: Chemistry 154.002 Experiment 13 Physical Properties of Water Lauren Best Partner: Glenn Cormack 3/5/08 TA: Lek 1. Objective Determine the normal freezing point and melting point of water. With this information, the heat of fusion is to be measured. 2. Procedure A) Water Cooling Curve – The Normal Freezing Point of Water 1. Prepare for data collection by connecting the temperature probe and by preparing the computer for data collection. All data will be displayed on the computer screen. 2. Put 10mL of deionized water into an 8” test tube. Mount the test tube to the ring stand with a utility clamp. Place the temperature probe inside the test tube, making sure the tip stays centered in the water. 3. Using 200 g of ice and 60 g of NaCl, prepare a low-temperature bath. Use a glass thermometer to check the temperature of the bath. The temperature needs to be at least -10 ° C. Make sure to stir in order to keep the temperature low....
