Recommended Prerequisites

Basic knowledge of chemistry, phyiscs and mathematics from secondary school.

Teaching Methods

Practical laboratory classes; during classes students have to register the observations in lab notebooks. In addition students fill a lab report in order to consolidate the knowledge acquired during experimental work.

Learning Outcomes

The objective of this curricular unit is to provide to students an introduction to classical analytical techniques and unitary operations that are essential to good practices in chemical laboratories.

The student must acquire skills in applying chemical knowledge in the interpretation of experimental data using graphical and statistical methods;  recognizing and implementing good lab practices for acquiring experimental results with quality; safe manipulating of chemical substances, taking into account their physical and chemical properties, recognizing specific dangers in their use; observation and measurement of chemical properties, changes and transformations, making reliable registrations in lab notebooks; elaborating objective lab reports.
