Yes, it is possible to extract iodine completely from its aqueous solution using carbon disulfide as a solvent. This process is known as solvent extraction or liquid-liquid extraction.

To extract iodine from an aqueous solution using carbon disulfide, you can follow these steps:

1. Prepare the iodine-containing aqueous solution in a separate container.
2. In a separating funnel, add the iodine-containing aqueous solution and carbon disulfide.
3. Shake the separating funnel gently, allowing the two immiscible solvents (water and carbon disulfide) to mix and form two distinct layers.
4. Wait until the two layers separate completely, with the denser carbon disulfide layer settling at the bottom.
5. Carefully open the stopcock of the separating funnel, allowing the aqueous layer to drain slowly from the bottom while keeping the carbon disulfide layer intact.
6. Collect the carbon disulfide layer containing the extracted iodine in a separate container.

Comment: Carbon disulfide is a suitable solvent for extracting iodine from its aqueous solution because iodine is more soluble in carbon disulfide than in water. The immiscibility of the two solvents allows for the separation of iodine into the carbon disulfide layer during the extraction process. However, it is important to note that while the extraction process can remove a significant amount of iodine, it may not be able to extract 100% of the iodine molecules.
