Give an example of a mixture which exhibits following characteristics.
(a) Two non-mixcible components. (b) Two volatile components with appreciable difference in boiling points.
(c ) Two coloured components. (d) Water containing certain suspended particles.
(e) Water containing a soluble salt. (f) A volatile and a non-volatile component.

Explanation

(a) Carbon disulphide and water. The separation can be done by a separating funnel.
(b) Ethyl alcohol and ether. The separation can be done by simple distillation. However, proper precaution must be taken since ether vapours catch fire.
(c ) A mixture of blue-black ink. Separation can be done by chromatography.
(d) A mixture of copper sulphate and water. The separation can be done by concentration followed by cooling the concentrated solution (crystallisation).
(e) A mixture of naphthalene and solution chloride. Separation can be done in a china dish, covered by a funnel. The process is called sublimation. Naphthalene gets separated as sublimate leaving behind sodium chloride.
