Question

In a mixture two substance with different densities can be separated by:- ​

Answer 1

Answer:

If they do not mix, then they can be separated using gravity. There are special separation funnels for that kind of operation. If the two liquids mix, or dissolve in each other, the difference in density is irrelevant and you need to find other ways to separate them.

Chromatography is used to separate mixtures of coloured compounds. The technique used depends on whether the liquids dissolve in each other, and so are miscible, or if they are immiscible.
