By using chromatography method, different dyes in ink can be separated , (A)-(iv). Different gases present in liquid air can be separated at different heights by fractional distillation, (B)-(iii). Crystals of copper sulphate are obtained from its aqueous solution by evaporation and crystallisation, (C)-(ii). Distillation is used for the separation of components of a mixture containing two miscible liquids which boil without decomposition and have sufficient difference (30-50 K) in their boiling points e.g, acetone (b.p. = 329 K) and water (b.p. = 373 K), (D)-(i).
