Iodine can be separated from a mixture of Iodine and Potassium Chloride by

A. Sedimentation

B. Filtration

C. Sublimation

D. Distillation

Answer: Option C

Solution(By Examveda Team)

Iodine is well known to sublime (change from solid to gas without becoming liquid inbetween) when heated. However sodium chloride has a melting point much higher than that of iodine. Therefore, a mixture of iodine and sodium chloride can be separated by using a sublimation apparatus, with solid iodine collected by condensation on a cold surface.
