Question

(a)Name a technique to seperate a mixture of two or more miscible liquids for which difference in boiling point is less than 25 k ?
(b)describe the structure of the column used in the above technique . why is it used ?

Answer 1

Answer:

(a) fractional distillation

(b) the column consists of a distilling flask, a fractionating column, a thermometer, a bunsen burner, and a beaker to collect the distilled liquid. it is used to separate liquid with close boiling points also, the fractionating has glass beads and a large surface area for condensation and vaporization of liquid

Explanation:

fractional distillation is used to separate liquids with close boiling points
