Learning Achievements (Dublin Descriptors)
The student must show mastery of basic knowledge related to the equilibrium in aqueous solution and apply to all analytical techniques that rely on them as the gravimetric and volumetric analysis. It must also have the fundamental knowledge for understanding the most common instrumental analytical techniques (chromatography, spectroscopy).
- The student will have to show an understanding of the concepts and theories provided by the course; It must be able to propose the most suitable methods such or quantitative analysis of different types of samples .
- The student will demonstrate the ability to use knowledge and concepts that allow to reason according to the specific logic of the discipline. Must be able, in particular, to apply the theoretical knowledge acquired in specific laboratory practices.
-The student will have to show a 'proper skills to effectively communicate the knowledge acquired.
