Question

Explain the method by which carbon tetrachloride ,water and ethyl alcohol mixture can be separated?

Answer 1

The solution is as follows:

1. The boiling points of these compounds are as follows:

Carbon tetrachloride 76⁰C
Ethanol 78⁰C
Water 100⁰C

2. As we see, there is a large difference between the boiling point of water and mixture of CC₄ and ethanol, we can separate water by simple distillation.

3. Now a there is a very little difference between the boiling points of of CCl₄ and ethanol are separated by fractional distillation. Or we can use separating funnel to separate them as they are not miscible with each other but distillation ensures a pure product.
