Well, darling, you can't make 90% ethanol from 100% ethanol because, sweetie, 100% means it's already pure ethanol. You can dilute it with a calculated amount of water to get to 90%, but you ain't changing that 100% ethanol into something else. So, mix it up with water like a fancy cocktail and voilà, you've got yourself some 90% ethanol.
What else can I help you with?
Is it possible to have an absolute alcohol from ninety percent ethanol using fractional distillation?
No, it is not possible to achieve absolute alcohol (100% ethanol) through fractional distillation of a 90% ethanol solution. Fractional distillation can only separate the components present in the solution, not create new ones. To obtain absolute alcohol, additional methods such as azeotropic distillation or molecular sieves are needed.
Why there is no 100 ethanol?
most "absolute" ethanol used in the lab is 95% ethanol by volume,this is due to the fact the ethanol is very miscible with water so its difficult to remove all the water that is present in the atmosphere,it is possible to get 100 alcohol but it is an awkward process and generally 95 does the job just fine
What is a mixture of ethanol and gasoline called?
A mixture of ethanol and gasoline is called gasohol or E10. Gasohol typically contains 10% ethanol and 90% gasoline. It is used as a fuel for vehicles that can run on ethanol blends.
Is gasohol a homogeneous mixture?
Ethylene glycol and hexane is not a homogeneous mixture. This is because hexane cannot interact with ethylene glycol due to lack of dipoles.
How do make a percent sucrose solution?
To make a percent sucrose solution, dissolve a specific weight of sucrose in a specific volume of water. For example, to make a 10% sucrose solution, dissolve 10 grams of sucrose in 90 mL of water. The formula to calculate the amount of sucrose needed is: (percent sucrose/100) x volume of solution = weight of sucrose (in grams).
