This is really cool...I had students use this site and compare their experiences to when we did the iodine clock reaction in the general chemistry lab. It was easy to supplement the reactions the students ran in lab with the simulations. Students could obtain more results without creating more waste or taking more time. This simulation could even be used in place of an actual lab for classes without lab access or for distance-learning courses. Here are two sample student comments comparing the two labs:

"I think I learned more in this lab than in the real lab. This is the kind of thing I will remember for a long time. Thanks I would have liked to do more of this in the labs."

"I like to do hands on things so the lab was a lot more fun to me than the computer, but it was easier to see the concept behind the experiment on the computer."

Technical Remarks:

The simulation works very well and was easy for students to use.
Used in course
