2. What type of liquid solvent is the best to dissolve ionic solids in?
3. How could you make a saturated solution unsaturated?
4. What will increasing the temperature of a liquid do the solubility of a solid in a liquid?
5. What are the properties of a solution?
6. What happens to the boiling point of a solution as a nonvolatile solute is added to the solvent?
7. What is actually freezing at the freezing point of a solution?
8. What can we say about a solution in which the rate of dissolving of a substance is greater that the rate at which the substance is crystallizing out of solution?
9. Name the factors that affect the solubility of one substance in another.
10. What factors can increase the rate of dissolving of a solid in a liquid?
11. How many phases are present in a solution of sugar and water?
12. If a crystal of a substance readily dissolves in a water solution of the substance, what can we say about the original solution?
13. What can we say about a solution in which adding a small crystal of the solute to the solution results in considerable crystallization?
14. Are saturated solutions dilute or concentrated?
15. What happens to the concentration of NaCl if water is added to a solution of NaCl?
16. Name some colligative properties.
17. What do the values of freezing point depression and boiling point elevation both depend on?
