Answer
On heating the mixture, camphor will evaporates as it is a sublime substance. Its vapours can be collected which will solidify on cooling. Common salt and chalk powder mixture is then mixed in water. Common salt gets dissolved in water while chalk powder does not. Then by filtration, chalk powder is removed from the solution as it gets deposited in filter paper. The filtrate contains water and common salt. Common salt can be separated from water by evaporation process.
