Abstract
Practical introduction to important experimental methods in physical and analytical chemistry
Objective
The students have to carry out selected experiments in physical chemistry and to evaluate measurement data. They acquire a good knowledge about the most important practical techniques in analytical chemistry. Laboratory reports have to be written to each experiment.
Content
Physical chemistry part: Integrated in this laboratory work is a short recapitulation of statistics and analysis of measurement data, writing of experimental reports with regard to publication of scientific works. Basic physical chemistry experiments (a maximum of six experiments form the following selection): 1. liquid-vapour phase diagram, distillation (with separation by gas chromatography); 2. solid-liquid phase diagram; 3. cryoscopy; 4. solubility and de-mixing equilibria; 5. distribution equilibria (including pH dependence); 6. kinetics; 7. heat of combustion; 8. electromotive force; 9. electrical conductivity of solutions; 10. surface tension; 11. viscosity measurements. - Analytical chemistry part: Integrated in the laboratory work are obligatory spectroscopic exercises in an accompanying tutorial. 1. Introduction to the concept of sampling, quantitative elemental analysis and trace analysis, atomic spectroscopic methods, comparative measurements with electrochemical methods; 2. Separation methods, their principles and optimisation: comparison of the different chromatographic methods, effect of the stationary and mobile phases, common errors/artefacts, thin layer chromatography, liquid chromatography, gas chromatography (injection methods). 3. Spectroscopic methods in organic structure determination: recording of infrared spectra, recording of UV spectra, recording technique in NMR.
