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.
The course is organized in lectures (48 hours) in which the theoretical principles of qualitative and quantitative analysis and their applications will be illustrated. Numerical exercises related to analytical problems will also be performed in order to deepen the theoretical concepts covered in the course.
