Question

Two liquids ‘A’ and ‘B’ are miscible with each other at room temperature. Which separation technique will you apply to separate the mixture of ’A’ and ‘B’ if the difference in their boiling point is 20 0C?

Answer 1

Answer- We will use the process of FRACTIONAL DISTILLATION.
Reason--> 1. Both liquids are miscible with each other.2. Difference in boiling point is less than 25°C i.e. 20°C.
¬Principle- 1. Two or more than 2 miscible liquids should be there.2. Difference in boiling points should be less than 25°C/25 K.3. Liquids shouldn't decompose on heating.
¬Applications- 1. To separate chloroform and Benzene.2. To separate Ethyl Alcohol from water.3. To separate components of petroleum.4. To separate components of air.
