How do you make iodine from potassium iodide?

Answer 1

Run an electrical current through the solution while in an electrolytic cell. This is a process called Electrolysis which causes the KI molecules to dissociate to form K+ and I- Iodide will eventually come to equilibrium with itself to get rid of the negative charge and form I2

Answer 2

To make iodine from potassium iodide, you can add an oxidizing agent like hydrogen peroxide to a solution of potassium iodide. This will cause the iodide ions to oxidize into molecular iodine, which will precipitate out of the solution. The iodine can then be collected and purified through further chemical processes.
