In this animation we will explore the solution process at the particulate level. Answer the questions at the appropriate point in the animation. Clicking in the animation window will start the animation.

Important do not press the enter key or the Return key while you are answering these questions. Your Browser will interpret either key the same as clicking the mouse on the Submit button. So BE CAREFUL!

Give me some responses to the questions below and I'll give you some extra credit.

Laboratory Section:

1. Before the animation is started there are two phases shown, identify each phase and its location in the container (ie, phase at the top, phase at the bottom.) What do the colored circles represent?

2. Start the animation. What did you observe happening when the phase at the top was added to the phase on the bottom?

3. Briefly define solute and solvent.

4. In terms of the yellow (solute) particles, how does their arrangement after mixing differ from their initial arrangement? (Note: you might discuss the change in terms of entropy.)

5. In terms of the blue (solvent) particles, how does their arrangement after mixing differ from their initial arrangement? (Note: you might discuss the change in terms of entropy.)

6. The animation above depicts the solution process at the microscopic level. Which of the following movies best depicts the solution process at the macroscopic level? Movie1 Movie2 Briefly explain why the movie you selected depicts the solution process, and why the other movie does not.

(Note: You need to remember the userid (chem1515) and password to see these movies. E-mail dr. g. if you have forgotten the password.)

7. Is there anything about this PLE that you feel you do not understand? List your concerns/questions.
