Ethanol is used because the Aspirin can dissolve into it however when it is then added into the water the aspirin can dissolve so comes back and re appears and as it reappears it comes back purer than before

Why use recrystallisation for the purification of aspirin?
i do not have any answer,i want the answer
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 much water should be used for the recrystallisation of benzoic acid?
depends on how much benzoic acid you use. if you have 0.5g of benzoic acid , you need 30ml of water as a solvent.
In iodoform test can you use ethanol instead of water?
no, because ethanol gives iodoform reactions
Why is it not possible to use ethanol to extract an organic compound from water?
Because ethanol and water are miscible solutions, that is that they can mix together or co-dissolve.
Why is ethanol not use as an electrolyte?
The dissociation is not so important.
What is a major drawback to the use of ethanol based energy?
Burning ethanol releases greenhouse gases. CO2 and water vapour
What did north west mesopotamia people use to water there land?
ethanol
How can you make an aspirin dissolve faster?
By using warm water and stirring it around
Can you use ethanol in extraction with water?
No, ethanol and water are miscible. For an extraction, you want two solvents that are immiscible (mutually insoluble). Standard choices for the organic phase are ethyl acetate or dichloromethane. For the aqueous phase, use water, aqueous acid or aqueous base, depending on the compound you are trying to isolate.
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
Solution of water and aspirin an acid?
Yes it will be weakly acidic. Aspirin's scientific name is acetylsalicylic acid, with a pKa of 3.5. This would mean that for a solution of 0.1 M aspirin, the pH of the solution would be approximately 2.26.
