1. What are the similarities and diferences between miscibility and solubility?

2. What are the differences and similarities between molarity and molality? What are the disadvantages and advantage sof each unit?

3. Every pure substance has a definite and fixed set of physical and chemical properties. A solution is prepared by dissolving one pure substance in another. Is it reasonable to expect that the solution will also have a definite and fixed set of properties that are different from the properties of either component? Explain ur answer.

4. Describe the forces that promote the dissolving of a solid solute in a liquid solvent.

5. Which of the following solutes do u expect to be more soluble in water than in cychlohexane: (a) formic acid, (b) benzene, (c) methylamine, (d) tetrafluoramethane? Explain ur choice.
