Cool Chemistry EXPERIMENTS IN 3rd YEAR ANALYTICAL CHEMISTRY

Each experiment requires two days to complete.  Students work in pairs and analyse their own "unknown" sample in each experiment. 


    

  1. 
Polarography:  The purpose of this
experiment is to illustrate the principles of polarography
and
the analytical applications of the Ilkovic Equation via the analysis of
Cd.
    2. 

  2. 
Computer Controlled Acid/Base Titration: 
Using LabView software, students will learn how computers can assist in
the running, acquisition of data and data analysis while performing an
acid/base titration on an unknown compound.
    3. 

    

  3. 
UV/VS Spectrophotometry:  Investigate
the quantification of iron usiing Beer's Law.  Formaiton of the Fe(o-phen)3
complex in solution is followed by measurement of the absorbance of the
solution using the
HP8452 photodiode array spectrophotometer.
    4. 

    

  4. 
Atomic Absorption Spectroscopy: 
Introduction to atomic
absorption spectroscopy (AAS).  Investigate some of the instrumental
and solution parameters that are of importance for optimization of the
analytical signal, and to investigate the quantification of iron and zinc
using Beer's law.
    5. 

    

  5. 
Fluorometry:  To illustrate the
principles of fluorescence and their application in chemical analysis via
the use of a filter fluorometer for the determination of fluorescein.
    6. 

    

  6. 
High Performance Liquid Chromatography (HPLC): 
An introduction to separation science and chromatography via the separation
of some selected parabens using the
high performance liquid chromatographic technique.
    7. 

    

  7. 
Gas  Chromatography (GC): 
An introduction to the principles of chromatography via
GC separation of a suite (Benzaldehyde, Camphor and Pentylacetate)
of volatile organic species followed by the quantification of the same
using an internal standard approach.
