Question

Liquids which decompose on heating are purified by:

a)Solvent extraction
b)Fractional distillation
c)Distillation under reduced pressure
d)Crystallization
e)Other:_______​

Answer 1

Liquids that decompose on heating are purified by fractional distillation.

Option (b) is correct.

Explanation:

• Fractional distillation is a method that is used to separate the mixture of a liquid.
• If there are two liquid which decomposes on heating and needs to be separated then they are separated by this method.
• By this method, the liquid with less boiling point vaporizes and gets separated from another liquid.

Answer 2

b) Fractional Distillation
