Question
The mixture of iodine and salt can be separated by using:
- Coagulation
- Precipitation
- Sublimation
- All of these
Hint:
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.
