Question

how'll u separate a mixture containing kerosene and petrol (differ in their boiling points is more than 25degreeC)which are miscible with each other​

Answer 1

The mixture of two miscible liquids such as kerosene and petrol whose boiling points differ by more than 25°C can be easily separated by the technique of simple distillation. The separation is based upon the principle that the boiling point of more volatile (low building liquid of the mixture.

Answer 2

Explanation:

A mixture of kerosene and petrol can be separated by simple distillation method,as their boiling points differ by more than 25degree C.In distillation flask method the substance or object is half filled but heated slowly.As we know that petrol is more volatile than kerosene,it vaporises fastly.

Its vapours are condensed and also collected in a object or in receiver.The kerosine left in the distillation flask.Boiling point of petrol is 70 degree C to 120 degreeC.When temperature becomes constant,vapours of petrol start passing through the condenser and collect in the object.As soon as temperature rises again then at last heating is stopped and kerosene will left so we will obtain kerosene from the distillation flask method.
