The process used to separate a mixture of two or more miscible liquids when the difference in their boiling points is less than 25 ∘C is ___.
Fractional distillation
Miscible liquids are those which properly mix with each other to form a single phase and no distinct layers are visible.
To separate two miscible liquids with the large difference in boiling points i.e. more than 25 ∘C, distillation can be used. If the difference between the boiling points of miscible liquid is less than 25 ∘C then fractional distillation is used.
