Question

The mixture of iodine and salt can be separated by using:  

  1. Coagulation
  2. Precipitation
  3. Sublimation
  4. All of these

hintHint:

Sublimation is the transition of a substance directly from the solid phase to the gas phase without passing through the intermediate liquid phase

The correct answer is: Sublimation


    Iodine-salt mixture can be separated through sublimation. Iodine will sublime whereas salt will be left behind. Sublimation is a technique that helps chemists to purify. During sublimation, upon heating, a solid substance is converted to the gas phase without passing through the liquid phase.
