This experiment demonstrates the mass transfer of iodine from an aqueous solution to an organic layer through the use of an oxidizing agent. Complexed iodine, soluble in water as triiodide, forms a brown solution in the denser aqueous layer while free iodine forms a faint pink color in the organic solution. Upon addition of an oxidizing agent, such as bleach, to the bottom of the vial, the triiodide comp lex is oxidized to free iodine. The free iodine, which is only sparingly soluble in water, then undergoes diffusive mass transfer into the organic layer. In the end, the organic solvent becomes dark pink as io dine leaves the aqueous layer and the aqueous layer becomes clear.
