Sublimation
Sublimation can be used to purify:
Select the correct option:
Solution
Solids that vaporize without melting
Sublimation is a physical process where a substance changes directly from a solid to a gaseous state without passing through the liquid phase upon heating.
- Application: Useful for purifying solids that possess a high vapor pressure below their melting point.
- Examples: Naphthalene, Anthracene, Benzoic acid, Camphor, and Iodine.
- Non-sublimable solid impurities are left behind in the heating vessel, while the sublimed vapors are condensed back to pure solid on a cold surface.
