(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 same solvent.

Answer» (a) A mixture of naphthalene (volatile) and common salt (non-volatile). The separation can be done by sublimation.
(b) A mixture of acetone boiling point = `56^(@)C`) and water (boiling point = `100^(@)C`) separation can be done by distillation.
(c ) A mixture of kerosene oil and water. Separation can be done in a separating funnel.
(d) Same as in (a)
(e) A mixture of blue/black ink. Separation can be done by chromatography.
