Give the steps to separate a mixture of water and ethanol.

1) Heat the mixture in a flask. At 78 C the ethanol begins to boil, some water evaporates too. So a mixture of ethanol and water rises up the column. 2) The vapour condenses on the glass beads in the column making the beads hot. 3)When the beads reach about 78 C ethanol vapour can no longer condense on them, only the water vapour does. So the water drips into the flask, the ethanol goes into the condenser where it condenses and pure ethanol drips into the beaker. 4)Eventually, the thermometer reading rises above 78 C, a sign that all the ethanol has gone.
