2. Aluminum chloride was a product in step 6. How could you instruct your lab partner to recover it.
You need to provide more details.
To instruct your lab partner to recover aluminum chloride, follow these steps:
1. Prepare the necessary equipment: glassware, filters, an evaporating dish, and a heat source (e.g., Bunsen burner).
2. Begin by preparing a filtration setup. Place a filter paper inside a funnel and place the funnel over a clean, dry beaker.
3. Carefully transfer the mixture containing aluminum chloride into the filtration setup. The aluminum chloride may be in the form of a solid or dissolved in a solution.
4. Slowly pour the mixture into the filter paper, allowing the liquid (known as the filtrate) to pass through while leaving the aluminum chloride as a residue on the filter paper.
5. Once all the liquid has passed through, use a wash bottle to rinse the residue with a small amount of cold distilled water. This step helps remove any impurities that may be present.
6. Transfer the wet residue from the filter paper into an evaporating dish. Gently scrape off the aluminum chloride using a spatula or glass rod. Be careful not to lose any of the solid.
7. Spread the aluminum chloride evenly in the evaporating dish, ensuring a larger surface area for evaporation.
8. Place the evaporating dish on a heat source, such as a Bunsen burner, and apply gentle heat. The purpose of heating is to evaporate the remaining water, leaving behind the dry aluminum chloride.
9. Continuously monitor the evaporating dish, making sure that the heat is not too intense to avoid decomposition of the aluminum chloride. Stir the contents occasionally to aid in uniform evaporation.
10. Once all the water has evaporated, allow the evaporating dish to cool down to room temperature. At this stage, the dry aluminum chloride should be obtained.
11. Weigh the evaporating dish with the dry aluminum chloride to determine the yield. Remember to subtract the initial weight of the empty evaporating dish for accurate results.
12. Record your observations and data in your lab notebook for future reference.
By following these instructions, your lab partner should be able to recover aluminum chloride successfully.
