SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

Phase Separations cont’d

Students should be able to:

9.3. discuss the chemical Laboratory work on the
principles and use of steam extraction of essential oils
distillation; from plant materials.
Purification of
nitrobenzene and
phenylamine. Simple
calculations are required.

9.4. discuss the principles upon A discussion on partition
which solvent extraction is coefficient and simple
based; calculations are required.

9.5. select appropriate methods Conduct simple separation
of separation, given the experiments based on
physical and chemical solute partitioning
properties of the between two immiscible
components of a mixture; solvents. These could
include the separation of
an acid/base mixture.

9.6. perform distillation These should include (but
experiments; and, not be limited to) a
comparison of the
efficiency of separation of
ethanol in beer or rum by
simple and fractional
distillation.

9.7. cite examples of the Include petroleum, rum
applications of the and the fragrance
distillation methods used in industries.
various industries.
