Partitioning of Iodine in Solution

In the first photo, two funnels on stands are shown, one with a purple liquid and one with clear liquid. Two small flasks sit near each funnel. In the second photo, the liquids separate into brown and clear liquids.
 

Description: Equimolar solutions of Iodine in both hexane and water are shaken in a separatory funnel with either water or hexane. The Iodine in water is driven to the hexane layer, but not visa versa, as seen by the color of iodine.
