Objectives
Theoretical aspects :
The purpose of this course is to provide a guide to understanding the fundamental principles of the analytical technics of volumetric and instrumental methods.
Experiments :
With selected experiments the students are introduced in the practical aspects of volumetric and instrumental technics and how measurements are translated to reliable quantitative dates.
The results are qualified by concepts of quality control. A security report pays attention to the dangers associated to those chemical products.
