The document describes how to separate a solution containing ethanol, iodine, and LiNO3. Heating the mixture causes the low boiling ethanol and iodine to evaporate first, leaving behind the high boiling solid LiNO3. The ethanol-iodine mixture is then treated with toluene, which dissolves the iodine but not the ethanol, separating the two. Finally, evaporating the toluene recovers the iodine. The process separates all three original compounds from the solution.

How to separate the solution of ethanol, iodine, and LiNO3
Solution
LiNO3 is a high boiling solid. Heating the mixture allows low boiling ethanol and iodine to first
come out of the system. LiNO3 is left behind.
The mixture of ethanol and iodine is then treated with non-polar aromatic solvents such as
toluene. Iodine dissolves in it. Ethanol does not dissolve and is separated. Finally toluene is
evaporated to get iodine back.
So we have separated all three compounds.
