Learning outcomes

The course learning outcomes, specific knowledge, skills and competences of an appropriate level, which the students will acquire with the successful completion of the course are described.

Consult Appendix A

·     Description of the level of learning outcomes for each qualifications cycle, according to the Qualifications Framework of the European Higher Education Area

·     Descriptors for Levels 6, 7 & 8 of the European Qualifications Framework for Lifelong Learning and Appendix B

·     Guidelines for writing Learning Outcomes

The purpose of the course is for the students to understand the basic concepts and principles of Physical Chemistry, simple applications thereof, as well as the properties and uses of the most common physicochemical systems. To acquire skills, appropriate background for understanding the phenomena, which they will encounter in matters of Physical Processes and Instrumental Chemical Analysis.

After the end of the course students will be able to:

·        To know the laws of Thermodynamics, the statutory and non-statutory quantities of a system in order to understand their role in solutions, chemical kinetics and chemical equilibrium.

·        To know the properties of liquid and gaseous solutions as well as colloidal dispersion systems…

·        To participate in the conduct of laboratory exercises and to become competent in methodical problem solving

·        To know various methods for determining the surface tension of a liquid, the structure of colloidal systems, their preparation methods and their stability.

·        To understand the concept of photochemical – chemical chain reactions, chemical equilibrium as well as equilibrium during the hydrolysis of acids and bases, to express the speed of reactions and perform the relevant calculations.

·        To know various methods of separating mixtures (gases, liquids) due to different adsorption or distribution in solid or liquid phase, to become familiar with the corresponding chromatograms and to recognize the different peaks.
