Question
Chapter 11, Problem 36AC
To determine
From the following options, salt solutions freeze at a lower temperature than pure because:
(a) more ionic bonds are present.
(b) salt solutions have a higher vapor pressure.
(c) ions get in the way of water molecules trying to form ice.
(d) salt naturally has a lower freezing point than water.

1. When a liquid becomes a solid does it expand or contract?
2.Predict why it is hard to elevate or depress the temperature of water.
3. Compare and contrast how solid solutes and gas solutes differ in their relationship to solubility. Is one more or less soluble than the other, and why?
4. Research one other solute that can depress the temperature of water. Provide the name of the solute and how far it will depress temperature. Does this surprise you?
5.Predict whether large salt crystals or small crystals would lower the temperature faster; explain your answer in detail.
a) If a solute dissolves in a solvent, can you retrieve the solute? b) If so, suggest a method to retrieve the solute from your Ziploc bag. c) If not, why not?
