Calcium sulphate (CaSO4) which is an inorganic compound and does not sublime can be separated from camphor which is an organic compound and sublimes by the simple technique of sublimation. Sublimation involves the direct conversion of a solid into gaseous state on heating without passing through the intervening liquid state and vice-versa on cooling. Camphor sublimes and gets deposited on the walls of the cooler portion of the funnel and CaSO4 remains as such. The two components can thus be separated.
