The assessments of the given statements on the nature of the fluids and
the fractional distillation processes are as follows;
a. TRUE
b. TRUE
c. FALSE
d. A fractionating column is a glass piece that contains metal pieces or glass beads
What are the correct points regarding fractional distillation?
Option a.
Multiple vaporization-condensation cycles enhances the separation of
the components of the mixture;
Thereby enabling purification of the samples that have boiling points
that are close.
Option a is therefore; TRUE
- a. Multiple vaporization-condensation cycles are needed to purify samples of relatively close boiling points. TRUE
Option b.
The Height Equivalent to Theoretical Plate, HETP, indicates the
efficiency of the separation, and the fractionating column.
Therefore, option b. is TRUE
- b. The column efficiency of a fractionating column can be assessed by HETP. TRUE
Option c.
After every condensation-vaporization cycle, the condensate contains
more of the more volatile, component and the vapor be comes enriched
in the lower boiling point component.
Therefore, option c is FALSE
- c. With every condensation-vaporization cycle, the vapors become enriched in the higher boiling point component. FALSE
Option d.
d. The location of a fractionating column is placed vertically between the
mixture to be separated and the 'Y' adaptor, and consist of a straight
tube containing pieces of metals or glass beads.
