The process which is used to separate a mixture of two or more miscible liquids for which the difference in boiling points is less than 25 K is Fractional distillation.
True
Mixtures with a small difference in boiling points cannot be separated using regular distillation process.
Example, different gases from the air and also fractions from petroleum products are separated through fractional distillation. It is the method of separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize.
This apparatus is similar to that of normal distillation, except that a fractionating column is fitted in between the distillation flask and the condenser. So, to separate a mixture of two or more miscible liquids (for which the difference in boiling points is less than 25 K), the process used is 'Fractional Distillation'. And the given statement is true.
