Analytical Chemistry II

Recommended Prerequisites

General Chemistry I and II, Physical Chemistry I e II, Analytical Chemistry I.

Teaching Methods

The teaching methods of the theoretical lectures and theoretical-practical classes aim at global learning of the discipline. The lectures allow going from in-depth concepts through to understanding of the various aspects of analytical chemistry. They are supported by presentations with simple texts, and by audiovisual media, with opportunity to discuss difficult concepts. The classes accompany the lectures with active participation of the students in the resolution of problems that are provided at the beginning of the semester and are the subject of study prior to the respective class.

Learning Outcomes

The objectives of the curricular unit are to know the fundamentals of different topics in analytical chemistry, to understand their importance and illustrate their varied applications. Competencies to be developed are:

- Knowledge and comprehension: understanding and use of concepts in chemistry, ability to summarise information, critical reasoning ability

- Application of knowledge and understanding: apply knowledge gained to problem-solving in new situations in the area of analytical chemistry

- Judgment/decision making: ability to interpret chemical problems within the general framework of analytical chemistry, know how to justify decisions both orally and written

- Communication: acquire skills that enable the communication of information, in a clear way, thus demonstrating that the fundamentals of analytical chemistry have been understood – Self-learning competences: gain competences which allow self-learning.
