Question

Fractional distillation is used to separated

A, an insoluble substance from a soluble volatile substance

B. substances which are adsorbed differently, and which differ in their solubility in a solvent

c. liquids with differing boiling points

D gas, liquid or solid impurities from a mixture​

Answer 1

Answer: Fractional distillation is used to separate liquids with differing boiling points

Step-by-step explanation:

Sublimation is used to separate volatile substance from a non volatile substance where volatile substance gets converted from solid to gas.

Fractional distillation is separation of a liquid mixture into fractions which differ in boiling points by means of distillation by use of a fractionating column.

Chromatography is a separation method where different rates of adsortion of different components is used to separate substances.
