Give an example each for the mixture having the following characteristics. Suggest a suitable method to separate the components of these mixtures.
(a) A volatile and a non-volatile component.
(b) Two volatile components with appreciable difference in boiling points.
(c) Two immiscible liquids.
(d) One of the components changes directly from solid to gaseous state.
(e) Two or more coloured constituents soluble in some solvent.

Explanation

(a) Sulphur (a yellow solid) and iodine (a violet crystalline solid) are both soluble in carbon disulphide `(CS_(2))` solvent. Separation can be done by sublimation. Iodine sublimes on heating while sulphur does not.
(b) Turpentine oil and water. Separation can be done with a separating funnel.
(c ) Ammonium chloride and common salt. Ammonium chloride directly changes to vapour state (sublimes).
