Is ethanol a reactant or a product?
Your question is not right.ethanol is also know as ethyl alcohol. When you take the preparations of ethanol,here it acts as product example ethane reacts with water to give ethanol C2H4+H2O gives C2H5OH in this example ethanol is a product. When we take chemical or physical properties of ethanol it act as reactent in the chemical equation. Example-combustion or burning of ethanol in air gives carbon dioxide and water. C2H5OH+3O2 gives 2CO2+3H20 in the above example ethanol is a reactent.
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 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.
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.
Why is fractional distillation is an appropriate technique to separate ethanol and water?
alcohol and water have different boiling point. i.e bp of alcohol is78C andwater is100C
What is the color of ethanol in physical properties?
Ethanol i.e. alcohol in its natural state is water white and transparent .
What are two physical properties that could not be used to distinguish between water and ethanol?
Color and volatility
What physical properties are used to separate salt from water?
the physical properties are gold and ice cream due to the salt being covered by the gold and the ice cream being in my belly.
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.
When do water undergo a change in physical properties?
These physical properties depends on the water temperature.
What are the steps to Separate a Mixture?
It all depends on the substance and its physical properties. For example, salt water can be separated by boiling the water and letting the salt remain.
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

Why is paper's physical properties different from water's physical properties?
There are a lot of reasons why paper's physical properties differ from water's physical properties.Paper is a solid, water is a liquid.Water is transparent, paper is not.Water flows smoothly, paper does not.etc.
What are the physical properties of water cycle?
water
Describe an experiment used to find out whether there is any temperature change on mixing ethanol and water?
Measure equal amounts of water and ethanol in separate containers. Take temperature of both. Add ethanol to water and take temperature.
Do compound have their physical properties?
Yes water has a certain boiling point, a certain freezing point, it is colorless. these are physical prop. another liquid, like pure ethanol, will not freeze at the same temp nor does it boil at the same temp as water but it is colorless just like water. both are compounds
