Question

State two advantages of using simple distillation to form pure substances.

Answer 1

Answer:

Explanation:

Advantages of Fractional Distillation over Simple Distillation

In a fractional distillation setup, a fractionating column is typically placed between the distilling flask and head to increase the separation of liquids from the mixture. These columns have a larger surface area on which liquid-vapor equilibria can occur and thus more theoretical plates. Examples of fractionating columns are Vigreux and glass beads columns, which have six to eight theoretical plates.

In a simple distillation, a fractionating column is not used, and vapor from the distilling flask goes straight into condensation. It only has one or two theoretical plates, so it would not be effective for the separation of mixtures like L1, which requires more than four vaporization-condensation cycles to purify.
