Question

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

Solution 1

The process of sublimation is used to separate a mixture of camphor and calcium sulphate. In this process, the sublimable compound changes from solid to vapour state without passing through the liquid state. Camphor is a sublimable compound and calcium sulphate is a non-sublimable solid. Hence, on heating, camphor will sublime while calcium sulphate will be left behind.

Solution 2

Sublimation.Because camphor can sublime whereas CaSO4 does not.
