Summary:
- Sublimation is the change of state from a solid to a gas without passing through the liquid state.
- When iodine is heated sublimation can be readily observed.
- Dry ice is a substance that sublimes at atmospheric pressures.
- Ferrocene (an iron-containing compound) is usually purified by sublimating.
- A sample of ferrocene is gently heated causing it to sublime.
- The video below shows the sublimation and deposition of iodine in a round-bottom flask that contains ice.
