Question

Which mixture is separated by using the technique of sublimation?


Open in App
Solution

Sublimation:

  • A material immediately changes from the solid to the gas state through the separating process known as sublimation.
  • There is no liquid phase for the material. As a result, it serves as an example of a solid to gas transition within a substance's states.
  • At the lowest pressure at which any component may persist in the liquid form, this endothermic reaction occurs.
  • Deposition or de-sublimation refers to the process of changing the material from its gaseous state to its solid-state.
  • It is sublimation done the other way around.
  • Ammonium chloride(NH4Cl), Camphor(C10H16O), Anthracene(C14H10), and Naphthalene(C10H8) can sublime but common salt cannot sublime.

Final Answer:

Ammonium chloride(NH4Cl), Camphor(C10H16O), Anthracene(C14H10), and Naphthalene(C10H8) can be separated by using the technique of sublimation.
