How would you separate a sample of pure Iodine from a mixture of Iodine and lead2 sulphate
To separate pure iodine from a mixture of iodine and lead(II) sulfate, you can use the process of sublimation. Here are the steps:
1. Set up a distillation apparatus consisting of a round-bottom flask, a condenser, and a collection flask.
2. Place the mixture of iodine and lead(II) sulfate in the round-bottom flask.
3. Heat the round-bottom flask gently using a Bunsen burner or a hot plate. The goal is to heat the flask enough to sublimate iodine but not to melt lead(II) sulfate.
4. As the mixture is heated, iodine will vaporize and rise up the condenser where it will cool down and condense.
5. The condensed iodine will collect in the collection flask while lead(II) sulfate will remain in the round-bottom flask.
6. Continue heating until all the iodine has sublimed and collected in the collection flask.
7. Once all the iodine has been collected, remove the collection flask from the apparatus.
8. Carefully scrape the solid iodine from the walls of the collection flask using a spatula to obtain pure iodine.
Note: It is important to handle iodine with caution as it is toxic and can cause skin and eye irritation. Additionally, be cautious with the heating process as overheating may cause decomposition or evaporation of the lead(II) sulfate.
To separate a sample of pure iodine from a mixture of iodine and lead(II) sulfate, you can use a process called sublimation. Here are the steps to perform the separation:
1. Grind the mixture of iodine and lead(II) sulfate into a fine powder. This will increase the surface area, making it easier for the iodine to be separated.
2. Transfer the powdered mixture into a heat-resistant container, such as a porcelain dish or an evaporating dish.
3. Set up a distillation apparatus. This consists of a heating source, a condenser, and a collecting vessel. The condenser should be connected to the container with the mixture.
4. Apply heat to the container, starting with a low to moderate heat. This will cause the iodine to sublimate, meaning it will change from a solid directly to a gas without going through the liquid phase. The lead(II) sulfate will remain behind as a solid.
5. As the iodine vapor rises through the condenser, it will cool and condense back into solid iodine. The solid iodine will collect in the collecting vessel.
6. Once the sublimation process has finished, remove the collecting vessel containing the pure iodine.
7. Carefully separate the iodine from the collecting vessel and transfer it to a clean, dry container for storage.
By following these steps, you should be able to separate the pure iodine from the mixture of iodine and lead(II) sulfate using sublimation.
