Question

How one can use the sublimation process to separate different compounds from the mixture?

• A. Using an evaporation of the sublimable substance.
• B. Using evaporation and condensation of the sublimable substance.
• C. Using liquid to gas conversion.
• D. Using solid to liquid conversion

Answer 1

The correct option is B

Using evaporation and condensation of the sublimable substance.

Take a mixture of sublimable and non-sublimable substances and place it on an evaporating dish which is covered with an inverted flask plugged with cotton. Provide heat to the evaporating dish, the sublimable component evaporates and further condenses on the sides of the flask and the non-sublimable component remains in the evaporating dish.
