Sublimation

Vedclass · Answer

(A) $(1)$ Sublimation: It is the purification technique based on the principle that on heating,some solid substances change from solid to vapour state without passing through the liquid state.$(2)$ Distillation: It is used to separate volatile liquids from non-volatile impurities or liquids having a sufficient difference in their boiling points.$(3)$ Chromatography: It is based on the separation of components using stationary and mobile phases.$(4)$ Crystallization: It is based on the difference in the solubilities of the compound and its impurities in a suitable solvent.

List-$I$ (Purification technique)	List-$II$ (Mixture of organic compounds)
$(A)$ Distillation (simple)	$(I)$ Diesel + Petrol
$(B)$ Fractional distillation	$(II)$ Aniline + Water
$(C)$ Distillation under reduced pressure	$(III)$ Chloroform + Aniline
$(D)$ Steam distillation	$(IV)$ Glycerol + Spent-lye
