Sublimation
* Principle: Camphor is a solid that readily sublimates (changes directly from a solid to a gas) when heated. Sugar does not sublimate.
* Procedure:
1. Place the mixture in a shallow dish or beaker.
2. Cover the dish with a watch glass or a sheet of filter paper.
3. Gently heat the dish using a Bunsen burner or a hot plate.
4. The camphor will sublimate and condense on the cool surface above the mixture (the watch glass or filter paper).
5. Remove the condensed camphor, leaving the sugar behind.
Important Notes:
* Safety: Camphor is flammable, so handle it with care and use caution when heating it.
* Ventilation: Sublimation produces fumes. Work in a well-ventilated area or use a fume hood.
* Purity: The sublimed camphor may contain traces of impurities, so it's best to re-sublimate it for greater purity.
Alternative Method: Dissolving and Filtration
* Principle: Sugar dissolves in water, while camphor does not.
* Procedure:
1. Add water to the mixture.
2. Stir to dissolve the sugar.
3. Filter the mixture through a filter paper.
4. The sugar will pass through the filter paper in the solution, while the camphor will be retained on the filter paper.
5. You can recover the sugar by evaporating the water from the solution.
