Lesson 3: Dissolving Fullerenes

Some substances dissolve in water, while others require a solvent with different properties. The general solubility rule is that likes dissolve likes. This means that the more alike in their bonding type a solute is to a solvent, the more likely the solvent will dissolve the solute. Are you ready to dissolve into this lesson?

Doing the science

  1. Start the Buckyball Simulation by clicking on the "Sim" tab.
  2. Click on the fullerene (C60) container and drag a chunk to the empty beaker on the tabletop.
  3. Click on the container of "Water."
  4. Note and record in Table 1 whether or not the C60 dissolved in the water.
  5. Click the "Reset" button at the bottom of the screen.
  6. Click on the fullerene (C60) container and drag a chunk to the empty beaker
  7. Click the container of "Benzene."
  8. Note and record in Table 1 whether or not the C60 dissolved in the benzene.

Sample

Dissolve in Water? (Yes/No)

Dissolve in Benzene? (Yes/No)

C60

Do You Understand?

  1. Is the bonding in C60 more like the bonding in water or in benzene? Please explain your response.


  2. Water is a polar molecule, while benzene is a nonpolar molecule. How would you classify C60, as polar or nonpolar? Please explain your response.


  3. Methanol is a highly polar substance. Would you expect C60 to dissolve in a beaker filled with methanol? Please explain your response.
