Question

25. A mixture contains two liquids A and B, which differ in their boiling points less than 20 K suggest a suitable
process to separate them. Draw a neat labelled diagram to explain this process.
OR
With the help of a flow diagram, show the process of obtaining different gases from air, if the boiling point of
oxygen, argon and nitrogen are 183° C, - 186° C and - 196°C respectively, which gas gets liquefied first as the
air is cooled?​

Answer 1

Answer:

here it is your answer

Explanation:

Separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column is called fractional distillation. In other words, separation process in which the volatile components (having different boiling points) and the difference is less than 25 K of a mixture (such as crude oil) are split from one another by heating the mixture in a column and collecting and condensing the vapours drawn from different levels of the column.
