1. List the IMF (not the type of base particles that exerts the force) from lowest to highest strength. 
 
 
 
2. List the base particles from highest IMF to lowest IMF. Don't forget that polar molecular have two different IMF (explain in your answer). 
 
 
 
3. Where do the basic particles of the solute go when they are "dissolved" into the solvent? 
 
 
 
4. What phrase are you suppose to memorize so that you will know when two different substance will "dissolving"? 
 
 
 
5. If you have carbon tetrafluoride and water, do they dissolve (since it is two liquids, it is called miscible) to create a solution? Explain. (Hint: Have to determine IMF for each substance first). 
 
 
 
 
 
 
 
6a. What kind of solution do you have if you added 14.5g of potassium nitrate to 100.mL (equal to 100.g) of water at 30&deg;C? Use your Solubility curve to help. 
 
 
6b. Same solution as in 6a including temperature except you added 60.g of solute in 100.g of water, 
 
 
7. Looking at your Solubility curve, you see that increasing temperature causes most of the solute (solids) to increase their Solubility (how much they can dissolve in given mass of water) but ammonia, NH3, (a gas) actually decreases. What is the one explanation that explains this. (Hint: What happens to the solvent when you add temperature in regardless of the type of solute). 
 
 
 
 
 
8. Please circle the correct answer.
a. Freezing point (FP) depression: FPsolution > FPpure solvent or 
FPsolution < FPpure solvent 
 
 
b. Boiling point (BP) elevation: BPsolution > BPpure solvent or 
BPsolution < BPpure solvent 
 
 
c. For the above two physical phenomena, what phrase am I making you memorize that explains these phenomena.
