Competences |
| Students are able to carry out basic physico-chemical experiments independently according to instructions in order to determine various thermodynamic, kinetic and electrochemical parameters and physico-chemical properties of materials. They are familiar with the safety-related principles in the physico-chemical laboratory and are able to implement them. Students have knowledge and understanding of the essential facts, concepts, principles and theories from various areas of physical chemistry and can thus describe chemical systems on the basis of their macroscopic properties.

| In particular, on completion of the course they will be able to
• correctly perform a range of experimental physico-chemical procedures and use standard laboratory equipment and instruments, including thermostats, calorimeters, manometers, potentiometers and conductometers, according to instructions. (k3, k6)
• plan and independently carry out an experiment according to instructions and document their laboratory work in record books. (k3)
• document their results appropriately, e.g. record experimental data in tabular form and create various visualisations. (k3, k4)
• determine physico-chemical parameters and/or properties and experimental errors from experimental measurements. (k4)
• critically analyse and interpret the experimental results and draw reasonable, accurate conclusions. (k5)
• evaluate the basic safety aspects of physico-chemical experiments. (k5)

The course consists of 12 individual experiments dealing with the following physico-chemical topics in which students determine the properties of liquids and solids.
1. In ‘thermodynamics’, the understanding of the concept of the heat of reaction, the experimental procedure for determining the heat of reaction and the significance of the water equivalent of the calorimeter is taught.
2.Through the interpretation of ‘phase equilibria’, students will be able to express the stability of the phases in the pure substance and determine the influence of pressure on the vapour pressure
3. The study of ‘multiphase systems’ will gain an understanding of the concepts of phase, component and degree of freedom, the expression of the phase rule and phase diagrams. Basic concepts of ideal and real solution and mixtures are known.
4. ‘Kinetics’ experiments will provide the concept of chemical reaction rate, the meaning of the rate equation and the factors that influence the reaction rate (concentration, temperature and presence of catalysts) are developed. Students will understand selected physical methods used in the kinetic study of chemical reactions.
5. Students are familiar with the various simple techniques of surface and interface analysis and can understand and describe the properties of free liquid surfaces, such as surface tension, capillarity, wetting and spreading. They are familiar with the concept of viscosity and can explain the theoretical principles. They can carry out simple experiments to determine this parameter. Students understand the phenomena of the interface between two phases and know the terms adsorption, adsorption kinetics and isotherms and can apply them.
