Iodine can be separated from a mixture of Iodine and Potassium Chloride by – (1) sedimentation (2) filtration (3) sublimation (4) distillation
by

1 Answer

Answer :

(3) sublimation Explanation: Iodine is well known to sublime (change from solid to gas without becoming liquid in between) 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.
