Best Answer

Water and Ethanol have different boiling points of 100 and 78 degree celcius.Therefore the best technique to be used for its separation is simple distillation.When this ids done, alcohol distils over at 78degrees leaving water behind thus the mixture has been separated.

What is miscible ethanol and water or water and oil?

Ethanol and water are miscible. Think of alcoholic drinks, the alcohol and water do not form separate layers.


Can you separate water and alcohol?

Previous answer: "You can use distillation to separate alcohol and water due to their different boiling points."Not quite. You can partially separate alcohol (ethanol) and water due to their different boiling points. Water and ethanol form what is called an azeotrope, meaning that at a certain concentration of ethanol (somewhere around 94-96% I think, not sure) you can not separate the water and ethanol to any greater extent through distillation. It is still possible to get 100% ethanol, but this has to be acheived either through exhaustively exact synthesis or using a water sequestration or drying agent on a water ethanol mixture and re-purifying the ethanol by whatever process is relevant.to separate this liquid -liquid mixture we must use-fractional distillationbecause alcohol for eg. methyl alcohol boils @ 64.7 C& water @ 100 C

How would you separate a mixture of water and ethanol?

By fractional distillation. Heat the mixture gently. As the temperature rises both liquids will evaporate and should be cooled and the condensate collected. The temperature will stabilise at around 78 deg C when all the remaining ethanol will evaporate.What you are left with is pure water. The condensate is mainly ethanol with a small quantity of water. It can be distilled again to increase its purity.

How do you separate isopropanol from a water-ethanol-isopropanol-solution?

One could try dimethyl- or diethyl-ether but it won't give a 'total' separation, only fractional: more isoprpanol than ethanol is extracted. Ether can be evaporated after this, and-or the whole procedure can be repeated.


How do you separate Ethanol and water?

Ethanol and water can be separated by fractional distillation. Fractional distillation separates liquid mixtures with different boiling points. Ethanol boils at a lower temperature than water. However, it forms a boiling azeotrope with water (azeotropes occur when solvent mixtures boil at a lower temperature than the component solvents). The azeotrope boils at 77.85 degrees, whereas pure ethanol boils at 78.4 degrees. The azeotrope is 96% ethanol and 4% water by volume. This is the maximum concentration of ethanol that can be achieved by simple distillation. Other methods of separating ethanol from water include using salts to make the water and ethanol phase-separate, using molecular sieves, using additives to change the azeotropic mixture, or distilling dry ethanol from wet ethanol that has been treated with a water-reactive metal, leaving behind the solid metal hydroxide.
