Question

What type of mixtures are separated by frictional distillation?

Answer 1

Answer:

Explanation:

Fractional distillation is the 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. It uses distillation to fractionate. Generally the component parts have boiling points that differ by less than 25 °C (45 °F) from each other under a pressure of one atmosphere. If the difference in boiling points is greater than 25 °C, a simple distillation is typically used.

Answer 2

Answer:

Fractional distillation is used to separate a mixture of liquids whose boiling points differ by less than 25 degree Celsius. In fractional distillation, the mixture of liquids is distilled through a fractionating column where the liquid with the lowest boiling point is distilled first and then the next liquid with the next higher boiling point and so on with the last liquid to be distilled having the highest boiling point.

Fractional distillation finds applications in the separation of components of crude oil and in the separation of nitrogen and oxygen from liquid air.
