To separate a mixture of iron and sulfur without using a magnet, you can use a process called "sublimation." Sublimation is the process of converting a solid directly into a gas without passing through the liquid phase. Here's a step-by-step explanation:
1. Start by placing the mixture of iron and sulfur in a container that can withstand heat, such as a porcelain dish.
2. Apply heat to the container using a Bunsen burner or a heat source. This will cause the sulfur to undergo sublimation since it has a lower melting point compared to iron.
3. As the sulfur sublimes, it will evaporate and form a gas, while the iron will remain as solid particles in the container.
4. Place a cold surface, such as a watch glass or a piece of cold ceramic or glass, above the mixture. The sublimated sulfur gas will cool down upon contact with the cold surface and re-solidify as yellow crystals.
5. The solidified sulfur can be collected from the cold surface using a spatula or any other suitable tool.
6. The remaining solid particles in the container will be iron since it does not undergo sublimation.
7. Finally, you can carefully pour out the iron particles, separating them from the sulfur.
This process uses the principle of different physical properties of the substances involved. Iron does not undergo sublimation, while sulfur does. By heating the mixture and allowing sulfur to sublime and then re-solidify, you can separate the two components.
