Question

Iodine-salt mixture can be separated through:

• A. simple distillation
• B. simple filtration
• C. sublimation
• D. fractional distillation

Answer 1

The correct option is C 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. A solid is heated under vacuum. The solid volatilizes and condenses as a purified compound on a cooled surface, a non-volatile residue of impurities is left behind.
