Outline a suitable procedure for separating a mixture of sulphur and sand.
Dissolve the S in CS2 and filter.Let the CS2 evaporate to recover the S
To separate a mixture of sulfur and sand, you can use a combination of physical and chemical methods. Here is a suitable procedure for the separation:
1. Collect the mixture: Gather the mixture of sulfur and sand in a container.
2. Grind the mixture: Use a mortar and pestle to grind the mixture thoroughly. This will help increase the surface area and enhance the efficiency of the separation process.
3. Use a magnet to remove iron particles (if present): Place a magnet near the mixture and slowly move it around to attract any iron particles. Since iron is magnetic, it will be pulled towards the magnet. Carefully remove the magnet along with the adhered iron particles.
4. Insoluble separation: Add the remaining mixture (without iron particles) to a container with water. Since sulfur is insoluble in water, it will float on the surface, while sand will sink to the bottom.
5. Decantation: Gently pour the water (with sulfur on top) into another container, leaving the sand behind.
6. Evaporation: Let the container containing the sulfur-water mixture sit undisturbed for some time. As the water slowly evaporates, the sulfur will start to solidify on the surface.
7. Collect the sulfur: Once the majority of the water has evaporated, carefully scrape off the solid sulfur from the container using a spatula or any other suitable tool.
8. Dry the sulfur: Place the collected sulfur on a filter paper or a drying tray and let it air dry. Ensure all the remaining water evaporates.
9. Collect the sand: After the water has been decanted from the sand, transfer the sand to a separate container. Allow the sand to dry completely, either by air drying or by using an oven at a low temperature.
By following these steps, you will be able to separate the mixture of sulfur and sand, obtaining purified samples of each component.
