Question

A mixture of sand and iodine can be separated by sublimation.

• A. True
• B. False

Answer 1

The correct option is A True

A mixture of sand and Iodine $\left({\mathrm{I}}_2\right)$ can be separated by sublimation.

Sublimation: The process of conversion of a substance from the solid state into gaseous state on heating directly without converting into liquid state.

• Example: Iodine, Camphor, Naphthalene, Anthracene
• $\mathrm{Iodine}\left(\mathrm{s}\right)\underset{\mathrm{Cool}}{\overset{\mathrm{Heat}}{\rightleftarrows }}\mathrm{Iodine}\left(\mathrm{g}\right)$
• When heated, Iodine can undergo sublimation whereas sand does not undergo sublimation. This leads to the separation of iodine from sand.

Hence, the given statement is true.
