How to obtain pure water and ethanol from a mixture of sea water and ethanol?
You would use distillation, in which the ethanol and water will boil at different temperatures.
How fractional distillation occurs in liquor?
Fractional distillation is the process of separating two (or more) liquids based upon differences in their boiling points. In liquor, ethanol has a lower boiling point than water, so a mixture of water and ethanol can be heated to allow the alcohol to boil. The vapor goes through a tube, is cooled and collected in a separate container, and a mixture that was mostly water is now mostly ethanol.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?
Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
Will letting water-sugar-yeast mixture ferment for long time affect the quantity of ethanol produced?
Letting a water, sugar, and yeast mixture ferment for a long time does not affect the quantity of ethanol produced.
Is ethyl alchohol a pure substance or mixture?
It is a pure substance.Added:Chemically speaking alcohol is meant to be ethanol, which is a pure compound with formula CH3CH2OH, it definitely is not a mixture, except when 'dissolved' in water (most stable solution: 4% water + 96% ethanol. (This is what you get when buying a bottle pure ethanol)
Is the mixture of ethanol in water a heterogeneous or homogeneous mixture?
The mixture water-ethanol is homogeneous.
Name the apparatus that can be used to separate a mixture of mustard oil and water. Explain its working?
separating funnel
Describe how distillation is used to separate a mixture of ethanol and water?
Distillation is based on the difference between boiling points of liquids. Ethanol is separated first.The distillation is possible only to an ethanol concentration of 95,63 % because an azeotropic mixture is formed.
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.
What are the chemicals that are present in the mixture of ethanol and water?
Of course, these substances are ethanol and water.
What conditions are needed to make ethanol from ethene and steam?
Heating a mixture of ethanol and water would produce a mixture of water vapor (steam) and ethanol vapor. Depending on the composition of the mixture, there could be more ethanol vapor than steam in the resulting gas mixture.

If a water ethanol mixture is distilled which will be collected first?
The ethanol will be distilled first and the water stays in the flask

How do you collect ethanol if it is in a mixture with water?
Distillation. Ethanol can be easily collected from water using distillation up to 97% purity.
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.
