ctions On Tsolution pure water - Freezing point depression Freezing Point C Freezing Point Depression 0°C 0 °℃ Couldn't get it to °℃ freeze °℃ 2M NaCl -6 °C °℃ 1M NaCl -4.4 °C 2M sucrose 10.8 °C QUESTIONS AND CONCLUSIONS A. Why is it so important to rinse all the glassware including the thermometer and graduated cylinder between? because it messes up the solutions and makes the experiment less accurate. B. Compare freezing points of 2 M solutions of sucrose and 2M NaCl, and discuss your results. Do you results support your hypothesis? Explain! No, it doesn't support my hypothesis because it's the same amount of particles but it has a different freezing temperature Solution Distilled water 4M NaCl Accessibility Investigate Focus DAR
C. Place a point on the Graph for the freezing points of 1, 2, 3 M of NaCl and 2 M sucrose. (Show your data: feel free to attach a photo of your graph to the assignment if you prefer!) 0 0 2 3 4 M/L Molar Concentrations D. Compare your results to Figure 11.10 page 314 of your textbook. Describe. It's similar 1 Temp. 2 3 4 5 6 or 7 8 9 -10 11 IN 12 13 -14
E. You used colligative properties in two ways in this experiment! Can you describe the a) exothermic transfer of energy from the water to the ice bath, and b) from the molar solutions to the water?
