How do I separate iodine from sodium chloride? | Socratic
Use the technique of sublimation. When iodine is heated gently, it undergoes sublimation, that is, it changes directly from a solid to a vapour. When the vapour hits a cold surface, it undergoes deposition, that is, changes from a gas back to a solid. Here's your experiment. Place mixture in an evaporating dish on a tripod in the fume hood. Invert a …
