Introduction
You have
just graduated with a Bachelor of Science in chemistry
and applied for the position of analytical chemist in
a newly established chemical company specialising in
testing services, research and development.
You have
shown a keen interest to assist the analytical laboratory
in the testing of the chemical nature and composition
of chemical samples from a wide spectrum of industries.
The information you gathered in experiments and analysis
will be used to develop new products, for quality control
and to refine manufacturing processes.
Task
Being one of the suitable candidates,
you are required to go through a battery of six virtual
laboratory analysis trials before you can be selected
for the final interview.
Your proficiency in qualitative
analysis, ability to make observations and proper records,
and knowledge of the physical and chemical properties
of substances are put to the test.
In order to qualify, you are required
to complete all six laboratory analysis sessions and
laboratory reports on the unknown chemical substances
assigned.
Resources
The company's analytical department
website:
Process:
-
Once you have entered the company, proceed to the
Virtual ChemLab.
-
There are six laboratory trials each beginning
with a laboratory training
manual. Read through the laboratory briefing in
detail and study
the experiments given carefully.
-
When you have completed the briefing, proceed to
the analysis lab
for the actual laboratory trial where the unknown
samples are tested.
Evaluation
At the end of each laboratory trial,
a complete laboratory report with all observations and
deductions recorded should be submitted before you proceed
to the next laboratory trial.
The candidate should demonstrate
the ability to:
- make accurate and relevant observations
- make precise and accurate records
- analyse and deduce the nature
of the unknown substances given
- identity of the unknown chemical
species given
- understand the chemical reactions
underlying the experiments
- represent the chemical reactions
in the experiments by writing chemical and ionic equations.
Conclusion
When you have completed the whole
series of laboratory trials, you would have a hands-on
experience of the work of an analytical chemist in the
research and testing laboratories. You would gain a
better insight of the strategies of qualitative analysis
used to test for unknown chemical substances. You would
also have an understanding of the real world application
of chemistry and the wide spectrum of substances that
can be analysed by qualitative analysis.
