Question

Explain the sublimation method of purifica-
ition of misture​

Answer 1

Answer:

Sublimation is the phase transition of a substance from solid into gas without passing through its intermediate liquid phase. It is an important technique used for purification of organic and inorganic solids. ... The reverse process in which the substance passes from its gaseous to its solid state, is called deposition.

Explanation:

Sublimation is a technique used by chemists to purify compounds. A solid is typically placed in a sublimation apparatus and heated under vacuum. Under this reduced pressure, the solid volatilizes and condenses as a purified compound on a cooled surface (cold finger), leaving a non-volatile residue of impurities behind.
