Question

A mixture of two or more miscible liquids, for which the difference in the boiling points is less than $25\mathrm{K}$ can be separated by the process called______.

Answer 1

Fractional distillation:

• “To separate a mixture of two or more miscible liquids for which the difference in boiling points is less than $25\mathrm{K}$, the fractional distillation process is used.”
• Fractional distillation involves the separation of two miscible liquids.
• For example mixture of ethanol and water can be separated by using fractional distillation.
• A simple fractionating column consists of a tube packed with glass beads. The beads provide a surface for the vapors to cool and condense repeatedly."
• The apparatus for fractional distillation is given below:

Hence, a mixture of two or more miscible liquids, for which the difference in the boiling points is less than $25\mathrm{K}$ can be separated by the process called fractional distillation.
