In order to separate the water from the ethanol at mixed room temperature with pressie of 1013 Kpa. The technique relies on the differential boiling points of the vapors that form a mixture above the flasks.
Thus the lower boiling points will lead to vaporize and rise through the column. Thus the remaining solution will bet concentrated and the amount of solvent it will decrease and substance with the lowest boiling point or room temperature will be collected first.
