Question

how will you separate a mixture containing kerosene and petrol ( difference in their boiling point is more than 25೦c), which are miscible with each other? explain with the neat diagram?​

Answer 1

Explanation:

Simple distillation can be used when the temperature difference between the boiling points of two miscible liquid is at least 25oC. The temperature difference between the boiling points of kerosene and petrol is 25oC. Hence, this mixture can be separated using simple distillation.

Answer 2

Answer:

A technique known as simple distillation can be used  to separate the mixture of miscible liquids, where  the difference in boiling point is more than 25°C, for  example; kerosene and petrol. The whole concept is  established on the volatility property of substances.  The following are the various steps in the process of  simple distillation:

1. In a distillation flask, take the mixture.
2. Treat the mixture with heat while a thermometer  is affix.
3. We observe evaporation of petrol as it has a low  boiling point.
4. As the vapours advance towards the condenser,  a dip in the temperature causes condensation of  the vapours into the liquid which can be accumulated  in a flask.
5. We notice that kerosene tends to remain in the  flask in a liquid state due to comparatively higher  boiling point.
6. Consequently, the liquids are separated.
