Question

Which mixture is separated by using the technique of sublimation?

Answer 1

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$\left({\mathrm{NH}}_4\mathrm{Cl}\right)$, Camphor$\left({\mathrm{C}}_{10}{\mathrm{H}}_{16}\mathrm{O}\right)$, Anthracene$\left({\mathrm{C}}_{14}{\mathrm{H}}_{10}\right)$, and Naphthalene$\left({\mathrm{C}}_{10}{\mathrm{H}}_8\right)$ can sublime but common salt cannot sublime.

Final Answer:

Ammonium chloride$\left({\mathrm{NH}}_4\mathrm{Cl}\right)$, Camphor$\left({\mathrm{C}}_{10}{\mathrm{H}}_{16}\mathrm{O}\right)$, Anthracene$\left({\mathrm{C}}_{14}{\mathrm{H}}_{10}\right)$, and Naphthalene$\left({\mathrm{C}}_{10}{\mathrm{H}}_8\right)$ can be separated by using the technique of sublimation.
