A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties. Various separation techniques exist in order to separate matter, including distillation, filtration, evaporation and chromatography.Whereas 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.
