Question

The suitable method is to separate the following components of the mixtures.

A) Two volatile liquids with appreciable differences in boiling points.

B) Two or more colored constituents soluble in some solvent.

• A. A - Fractional distillation, B - decantation
• B. A - Simple distillation, B - Evaporation
• C. A - Simple distillation, B - Chromatography
• D. A - Sublimation, B - Chromatography
• E. A - Sublimation, B - Simple distillation

Answer 1

Answer: (C)

A - Simple distillation, B - Chromatography

A) Two volatile liquids with an appreciable difference in boiling point are separated by a $\text{simple distillation}$ method. In this method, the liquid with a low boiling point is evaporated first. After condensation is collected in another vessel and by this way get separated from another liquid.

B) Two or more colored constituents are separated by the $\text{chromatography}$ method. In this method, the liquid which is more soluble in solvent moves faster and hence gets separated.

Hence, option $C$ is correct.
