Objectives

By attending lectures, students are expected to acquire some basic notions in Analytical Chemistry. Particular emphasis is put on the importance of analysis towards solving real-world problems.

Tutorials: Resolution examples are presented, as well as exercises on topics previously discussed in lectures.

Practical classes: set of 5 laboratory experiments designed in order to allow students understand theoretical concepts discussed in lectures an tutorials.
