Name a suitable technique of separation of the components from a mixture of calcium sulphate and camphor.
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.
Sublimation.Because camphor can sublime whereas CaSO4 does not.
