Prerequisites for admission
The general inorganic chemistry course is a prerequisite for full understanding of the lessons. In addition, students should have acquired the basics of mathematics and physics.
Teaching methods
The course is organized in lectures (32 hours) and classroom exercises (32 hours) in which the theoretical principles underlying the techniques of qualitative and quantitative analysis and their applications will be illustrated. Numerical exercises relating to analytical problems will also be carried out in order to better understand the theoretical concepts covered in the course.
