Answer Wiki. To venture a best guess: Fact is, the mineral oil is non-polar and the water is polar. So the diatomic iodine I2 will tend to migrate to the mineral oil because it is also non-polar. But some of the iodine dissociates to ionic iodine (I-), that constituent will migrate to the polar solvent, the water.
