Why is fractional distillation is an appropriate technique to separate ethanol and water?
Fractional distillation is appropriate to separate ethanol and water because they have different boiling points: ethanol at 78.4°C and water at 100°C. During fractional distillation, the mixture is heated to a temperature in between these boiling points, allowing the ethanol to vaporize but not the water. The vapor is then condensed and collected, resulting in separate ethanol and water fractions.
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 ways is ethanol similar to water?
Ethanol and water are both polar molecules, meaning they have a similar ability to dissolve substances. Both substances have high specific heat capacities, allowing them to absorb and retain heat effectively. Additionally, ethanol and water can both form hydrogen bonds with other molecules, influencing their physical and chemical properties.
Water and ethanol can be separated by heating the ethanol until it boils away from the water What type of change is this?
This is a physical change because the identity of the substances (water and ethanol) remains the same. The change is reversible, as both water and ethanol can be recovered from the separated mixture.
Is The colorless liquid ethanol burns in air a physical or chemical property?
ethanol is a type of alcohol, in the oxygenated hydrocarbon class of compounds. when it combines rapidly with oxygen in a combustion reaction, the ethanol is used up, and with oxygen forms carbon dioxide and water. ethanol is quite literally gone, it is broken down and reformed into new products, which is the definition of a chemical reaction.
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
Is dilute ethanol a mixture element or compound?
Dilute ethanol is a mixture because it consists of ethanol (a compound) combined with water and possibly other substances. In this case, the components retain their individual properties and can be separated by physical means, such as distillation. Therefore, while ethanol itself is a compound, its dilute form with water constitutes a 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.
Why is fractional distillation is an appropriate technique to separate ethanol and water?
Fractional distillation is appropriate to separate ethanol and water because they have different boiling points: ethanol at 78.4°C and water at 100°C.

The vapor is then condensed and collected, resulting in separate ethanol and water fractions.
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

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.
What is miscible ethanol and water or water and oil?
Ethanol is miscible with water, meaning they can mix in all proportions to form a homogeneous solution. Oil is immiscible with water, meaning they do not mix and instead form separate layers due to differences in polarity and intermolecular forces.
Why does foil not separate a mixture of chalk powdersugar and water?
Foil does not separate a mixture of chalk powder, sugar, and water because the physical properties of these substances are not effectively separated by the foil. Chalk powder and sugar are both soluble in water, meaning they dissolve and form a homogenous solution. The foil is not able to selectively separate the components of the mixture based on their solubility or other physical properties. To separate these substances effectively, techniques such as filtration or evaporation would be more appropriate.
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.
