Iodine is sublimable and it can be sublime while heated and it will be collected at the funnel stem.
Explanation:
- The solidification of Iodine here is basically by the sublimation. For the formation of sublime Iodine during the process of separating iodine from the chemical sodium chloride.
- During this process, the sublimation of sodium chloride doesn't happen, hence it can pass through the funnel but iodine forms into sublime which gets stuck on the way of funnel stem.
- And hence the resultant iodine we get is in the form of a solid which is termed as the solidification of iodine here.
