Name a suitable technique of separation of the components from a mixture of calcium sulphate and camphor.

Text Solution

Verified by Experts

A mixture of calcium sulphate and camphor can be separated by sublimation as camphor is sublimable whereas calcium sulphate is not. The mixture can also be separated by using a suitable organic solvent such as `C Cl_4, CHCl_3,` etc. Camphor is soluble whereas `CaSO_4` is not soluble in such a solvent.
