Solution

Mixture of iodine and sodium sulphate is separated by sublimation. Sublimation separates iodine and sodium sulphate. It is the process of a substance transitioning from a solid to a gaseous form without passing through the liquid state. The sublimation technique is used to separate mixtures that contain a sublimate with a volatile component from non-sublimate impurities. Iodine is used as a sublimate and sodium sulphate is used as a non-sublimate impurity in this mixture.
