Thinking about the partial specific volume (v-bar) of a solute and how it plays a role in AUC and analyte sedimentation, which of the following statements are true? (Assume that your solute is in pure water with a density of 1.00g/ml). There are two correct answers. Choose them both. The sedimentation coefficient of a particle with a v-bar of .75 ml/g would be greater than a particle with a v- bar of 1.20ml/g. The sedimentation coefficient of a particle with a v-bar of .75 ml/g would be less than a particle with a v-bar of 1.20ml/g. The particle with a v-bar of .75 ml/g would be more buoyant than a particle with a v-bar of 1.20ml/g. The particle with a v-bar of .75 ml/g would be less buoyant than a particle with a v-bar of 1.20ml/g.

6-16 Answer true or false. (a) Solubility is a physical property like melting point and boiling point. (b) All solutions are transparent—that is, you can see through them. (c) Most solutions can be separated into their components by physical methods such as distillation and chromatography.
A gaseous solute dissolves in water. The solution process has H=15 kJ. Its solubility at 22C and 6.00 atm is 0.0300 M. Would you expect the solubility to be greater or less at (a) 22C and 1 atm? (a) 18C and 6 atm? (a) 15C and 10 atm? (a) 35C and 3 atm?
You have read that adding a solute to a solvent can both increase the boiling point and decrease the freezing point. A friend of yours explains it to you like this: The solute and solvent can be like salt in water. The salt gets in the way of freezing in that it blocks the water molecules from joining together. The salt acts like a strong bond holding the water molecules together so that it is harder to boil. What do you say to your friend?
