Can steam distillation be done using a mixture of ethanol and water why and why not?
I hesitate to say that it literally can't be done, but ethanol dissolves things that water doesn't and the whole point of steam distillation is that the thing you're steam distilling needs to not be very soluble in water, so at best there's no real benefit from adding ethanol and at worst you can't separate your desired product out of the ethanol/water mix.
If you're not trying to separate it out, then ... you're not really doing a "steam distillation", you're doing an extraction. Gin, for example, is made by allowing the vapors from an ordinary distillation of ethanol/water (to increase ethanol content) to pass over/through substances like juniper berries to pick up some of the essential oils from these and give the resultant product flavor.

Can steam distillation of ethanol be done using a mixture of ethanol and water?
Yes, steam distillation of ethanol can be done using a mixture of ethanol and water. The mixture will allow for separation of the ethanol from the water by taking advantage of the difference in boiling points between the two compounds.
What conditions are needed to make ethanol from ethene and steam?
To produce ethanol from ethene and steam, you would need to carry out a catalytic hydration reaction using a suitable catalyst like phosphoric acid on silica or zeolite-based catalysts. This process requires high temperatures (150-300°C) and pressures (50-70 atm) to favor the formation of ethanol from ethene and steam. The reaction must be carefully controlled to prevent further reaction of ethanol to form undesirable byproducts.
How do you separate ethanol and sugar?
To separate ethanol and sugar, you can use a process called distillation. Ethanol has a lower boiling point than sugar, so by heating the mixture, the ethanol will vaporize first and can be collected as a separate component. This allows you to separate the ethanol from the sugar in the mixture.
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.
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.
Can steam distillation of ethanol be done using a mixture of ethanol and water?
Yes, steam distillation of ethanol can be done using a mixture of ethanol and water. The mixture will allow for separation of the ethanol from the water by taking advantage of the difference in boiling points between the two compounds.
How do you collect ethanol if it is in a mixture with water?
Ethanol can be separated from water through a process called fractional distillation, where the mixture is heated to a specific temperature at which ethanol vaporizes but water does not. The vapor is then condensed back into a liquid form to collect the ethanol.

Can ethanol be separated from sand and water?
Yes, ethanol can be separated from sand and water using distillation. Ethanol has a lower boiling point than water, so by heating the mixture, the ethanol will evaporate first and can be collected, leaving the sand and water behind.
How do you separate ethanol and sugar?
To separate ethanol and sugar, you can use a process called distillation. Ethanol has a lower boiling point than sugar, so by heating the mixture, the ethanol will vaporize first and can be collected as a separate component. This allows you to separate the ethanol from the sugar in the mixture.
How do you separat ethanol and water?
Ethanol and water can be separated using distillation. Since ethanol and water have different boiling points, heating the mixture will cause the ethanol to vaporize before the water. The vapor is then collected and condensed back into a liquid form, resulting in separate ethanol and water fractions.
What is the two possible methods that can be used to isolate eugenol?
Two possible methods to isolate eugenol are steam distillation, where eugenol can be extracted from cloves using steam, and solvent extraction, which involves using a solvent like ethanol to extract eugenol from cloves.
What is the process of making ethanol using ethene from crude oil?
Ethene from crude oil can be hydrated to produce ethanol through a process known as hydration. In this process, ethene is reacted with steam in the presence of a catalyst such as phosphoric acid to form ethanol. The ethanol produced can then be further purified through distillation.
Why steam is used as boiling source in steam distillation?
Steam is used as a boiling source in steam distillation because it allows for lower temperatures to be used in the distillation process, which is important for heat-sensitive compounds. The steam helps to carry the volatile components of the mixture being distilled, allowing for their separation from the non-volatile components. Additionally, using steam can reduce the risk of decomposition or degradation of the compounds being distilled.
What would be left in the flask when separating alcohol from water using fractional distillation?
In order to separate a mixture of alcohol (ethanol) and water, use a process known as fractional distillation. This technique relies on the principle that the compounds in the mixture have different boiling points. Since ethanol boils at a lower temperature (78.5 degrees C) than water, the alcohol vaporizes while the water remains a liquid. At some point, it will become an azeotropic mixture where the vapor has the same composition as the liquid. A good distillation column will produce an azeotropic mixture of 95 percent alcohol and 5 percent water. This ratio represents the most pure form of ethanol possible with distillation and is widely accepted as an industry standard.
