How Will You Separate a Mixture Containing Kerosene and Petrol (the Difference in Their Boiling Points is More Than 25ºc), Which Are Miscible With Each Other?

By K Balaji|Updated : November 9th, 2022

A mixture containing kerosene and petrol (the difference in their boiling points is more than 25ºC), which are miscible with each other can be separated using simple distillation.

Simple Distillation

  • It is a technique for dividing combinations based on how volatile boiling points are.
  • With the aid of a condenser, the mixture is evaporated in this way before being instantly cooled.
  • 95oC is the boiling point of gasoline.
  • This technique is used to separate a mixture of two miscible liquids whose boiling temperatures are greater than 25 degrees Celsius apart.
  • Kerosene has a boiling point between 150 and 180 o
  • Therefore, a straightforward distillation procedure can be used to separate the combination of gasoline and kerosene.

Procedure:

  • A beaker, water condenser, and Bunsen burner are additional parts, as indicated above.
  • Kerosene and gasoline are mixed together in this procedure in a distillation flask equipped with a thermometer.
  • Petrol, which has a lower boiling point than kerosene and is heated first, will evaporate and condense in the water condenser.
  • Kerosene is left in the distillation flask while the condensed gasoline is collected from the condenser outlet.

Thus, a mixture of kerosene and gasoline is separated in this manner.

Summary:-

How Will You Separate a Mixture Containing Kerosene and Petrol (the Difference in Their Boiling Points is More Than 25ºc), Which Are Miscible With Each Other?

Simple distillation can be used to separate a combination of kerosene and petrol (whose boiling temperatures are miscible with one another but differ by more than 25oC).
