Abuela asked Mirabel to perform an experiment on freezing point depression. The solution was prepared by dissolving 2.25 g of salt in 20.00 mL distilled water (density = 0.997 g mL1; Tf = 0 °C; kf = 1.86 °C m1). Mirabel determined the freezing point of the solution to be -3.48 °C. She later found out that the salt she used was sodium chloride that was contaminated with potassium chloride. 1. Calculate ATt for the experiment. 2. Calculate the molality of the solution. 3. Calculate the mass of potassium nitrate present in the salt sample.

You make 20.0 g of a sucrose (C12H22O11) and NaCl mixture and dissolve it in 1.00 kg water. The freezing point of this solution is found to be 0.426C. Assuming ideal behavior, calculate the mass percent composition of the original mixture, and the mole fraction of sucrose in the original mixture.
In terms of Raoults law, distinguish between an ideal liquid-liquid solution and a nonideal liquid-liquid solution. lf a solution is ideal, what is true about Hsoln, T for the solution formation, and the interactive forces within the pure solute and pure solvent as compared to the interactive forces within the solution? Give an example of an ideal solution. Answer the previous two questions for solutions that exhibit either negative or positive deviations from Raoults law.

Distinguish between a strong electrolyte, a weak electrolyte, and a nonelectrolyte. How can colligative properties be used to distinguish between them? What is the vant Hoff factor? Why is the observed freezing-point depression for electrolyte solutions sometimes less than the calculated value? Is the discrepancy greater for concentrated or dilute solutions?
