Understanding the Properties
* Camphor: It's a white, waxy solid with a strong, penetrating odor. It readily sublimes (changes directly from a solid to a gas) when heated.
* Sodium Chloride: A white, crystalline solid that is non-volatile (doesn't easily vaporize).
Separation Method: Sublimation
1. Setup:
* Place the mixture of camphor and sodium chloride in a suitable container.
* Cover the container with a funnel (or any inverted cone-shaped object).
* Place a cold surface (like a Petri dish filled with ice water) on top of the funnel.
2. Heating:
* Gently heat the container.
* The heat will cause the camphor to sublimate, turning it into a gas.
3. Collection:
* The camphor vapor will rise and condense on the cold surface of the funnel, forming pure camphor crystals.
4. Residue:
* The sodium chloride, which doesn't sublimate, will remain in the original container.
Safety Precautions:
* Ventilation: Camphor has a strong odor, so work in a well-ventilated area.
* Heat Source: Use a gentle heat source to avoid overheating the mixture.
* Fire: Camphor is flammable, so keep away from open flames.
