1. Partition Equilibrium
Iodine in Potassium Iodide
Iodine in cyclohexane

2. Partition Equilibrium
Cyclohexane has been added
Potassium Iodide has been added
What can you say about the position of equilibrium?
What would the partition co-efficient be? Estimate it.

3. Partition Equilibrium
The top layer is removed placed in a new tube to which potassium iodide is added
What can you say about the position of equilibrium when the top layer is removed and fresh potassium iodide added?
What would the partition co-efficient be now? Estimate it. What does this tell you?
