Organic Chemistry – Some Basic Principles and Techniques
How will you effect the separation of:
(i) Two immiscible liquids
(ii) Two miscible liquids
(iii) Two organic solids differing in solubility in same solvent ?
(i) By extraction with a separating funnel.
(ii) By fractional distillation.
(iii) By fractional crystallisation.
It is based on the difference in the solubilities of the compound and impurities in a suitable solvent.
