Question

how will you separate a mixture containing kerosene and petrol difference in the boiling points is more than 25 degree Celsius which are miscible with each other​

Answer 1

Explanation:

A technique known as simple distillation can be used to separate the mixture of miscible liquid where difference in boiling point is more than 25 degree Celsius. For example, kerosene and petrol. The whole concept is established on the votality property of substance.

Answer 2

$\blue{\huge{\mid{\underline{\mathcal{Answer :-}}}\mid}}$

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, to name a few – 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:

(a) In a distillation flask, take the mixture.

(b) Treat the mixture with heat while a thermometer is affix.

(c) We observe evaporation of petrol as it has a low boiling point.

(d) As the vapours advance towards the condenser, a dip in the temperature causes condensation of the vapours into liquid which can be accumulated in a flask.

(e) We notice that kerosene tends to remain in the flask in a liquid state due to comparatively higher boiling point.

(f) Consequently, the liquids are separated.
