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 else can I help you with?
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 could one determine whether a colorless liquid contained ethanol or ethanol and sucrose?
One could perform a simple density measurement to distinguish between ethanol and a mixture of ethanol and sucrose. Since sucrose has a higher density than ethanol, the density of the mixture would be higher than that of pure ethanol. Additionally, one could analyze the liquid using a technique such as gas chromatography to separate and identify the individual components present in the liquid.
What is the mixture of formaldehyde methanol and ethanol?
The mixture of formaldehyde, methanol, and ethanol would be a solution containing these three compounds. Formaldehyde is a gas at room temperature, while methanol and ethanol are liquids, so the mixture would likely be a liquid solution. Each compound has different properties, so the resulting mixture may display a combination of these properties depending on their concentrations.
What happens when ethanol is added to soap?
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.
What happens when ethanol is mixed with vinegar?
Probably nothing since vinegar is a dilute concentration of acetic acid...However if you had pure acetic acid & ethanol the two would react to form an ester called ethyl acetate at room temperature: CH3CH2OH (ethanol) + CH3COOH (acetic acid) <==> CH3COOCH2CH3 (ethyl acetate) + H2O However since it is an equilibrium reaction you'd have a mixture of the products & reactants & would need to separate the mixture. Under the presence of an acid catalyst (such as sulfuric acid) & continuously removing the water you can increase the yield of ethyl acetate.
How do you calculate the density of an ethanol-water mixture?
To calculate the density of an ethanol-water mixture, you would use the formula: Density (mass of ethanol mass of water) / (volume of ethanol volume of water) You would need to know the masses and volumes of both ethanol and water in the mixture. Then, you can plug these values into the formula to find the density of the mixture.
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.
Which of these methods would correctly separate the mixture?
To separate a mixture of salt and water, you can use evaporation: heat the mixture until the water evaporates, leaving behind the salt. Filtration can be used to separate a mixture of sand and water by pouring the mixture through a filter to trap the sand particles while allowing the water to pass through. Distillation is appropriate for separating a mixture of ethanol and water based on their different boiling points.
Why is iodine and ethanol mixture homogeneous and how can it be separarted?
An iodine and ethanol mixture is homogeneous because iodine dissolves well in ethanol, forming a single-phase solution where the iodine molecules are evenly distributed throughout the ethanol. To separate the mixture, one can use methods such as evaporation, where heating the solution would cause the ethanol to evaporate, leaving behind the iodine. Alternatively, fractional distillation can be employed to separate the two components based on their differing boiling points.
How would you separate a mixture of alchol and water?
boling it
Would you separate a mixture of alchol and water?
boling it
How would you separate a mixture of salt and rice?
To separate a mixture of salt and rice, you can use the method of dissolving the salt in water. When you add water to the mixture, the salt will dissolve while the rice will remain intact. Then, you can filter the mixture to separate the rice from the salty water. Finally, you can evaporate the water to obtain the salt.
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)
Why is it not possible to use ethanol to extract an organic compound from water?
Ethanol is miscible with water, which means that it mixes completely with water. As a result, using ethanol to extract an organic compound from water would not effectively separate the two substances since the compound would end up being mixed with both the water and the ethanol. This would make it difficult to isolate the organic compound.
What is the solute and solvent of tincture of iodine?
The solute would be iodine, and the solvent would be tincture
How would separate a mixture of sand and water?
get a strainer to get the sand out silly :)
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE?
First, determine the mass of ethanol in the mixture by dividing the mass of ethanol by the total mass of the mixture. Then, multiply the result by 100 to get the percentage by mass of ethanol in the mixture. For example, if a mixture contains 20g of ethanol in a total mass of 100g, the percentage by mass of ethanol would be (20g / 100g) * 100 = 20%.
