Class Analytical Chemistry

This curricular unit belongs to the curricular plan of this 1st cycle degree, whose concepts taught are important for the acquisition of knowledge of subsequent curricular units. This course aims to provide students with fundamental knowledge of the fundamental aspects of chemical processes associated with the different steps of a chemical analysis; the description and scientific basis of the different processes that make up a chemical analysis; and identifying and understanding the interaction of analytical chemistry with other areas of human activity (environmental, industrial analysis, ...).

This CU will use some active methodologies that promote greater student involvement in pedagogical activities, such as Flipped Classroom. This methodology will be used in the most practical and laboratory aspects, carried out in a collaborative environment (in groups) and always with peer assessment and self-assessment. Although laboratory work is not an innovative methodology, it is considered important to mention here since carrying it out helps in the consolidation of theoretical contents and in the students' involvement. In terms of digital technologies, the following will be used: moodle; data analyis (Excel or SPSS); Google Forms.
