Question

a mixture of acetone and benzene can be separated by ​

Answer 1

Answer:

THE ANSWER TO THIS QUESTION IS THE USAGE OF "AZEOTROPIC DISTILLATION METHOD"

Explanation:

The mixture of benzene and acetone cannot be separated by using any other distillation methods because of their similarities in boiling points.If distillation is used then the mixture starts to boil as a whole that is behaves like a single component thereby making it highly impossible to separate.This mixture so obtained by the distilling is called a "constant boiling mixture" .

And these type of mixtures are called azeotropes .

Now to separate them we add another organic compound which has a property to dissolve only one of the compounds of the mixture thereby the other being separated when heat is added.

These compounds are called "entrainers".

Examples of entrainers in separation of benzene and acetone includes toulene.

Answer 2

Answer: Fractional distillation
