Master: principles of selected physicochemical phenomena and methods. Correct interpretation of results and experimental data evaluation with use of computers is emphasized. Experiment list: viscosity, calorimetry, conductivity, vapor pressure, surface tension, liquid-vapor equilibria, solubility; phase equilibria, kinetics, sorption.
After completing the course, students will be able to: Apply the principles of safe work and good laboratory practice in physical and chemical measurements. Explain the theoretical principles of selected physical and chemical processes and measurement methods. Process experimental data using appropriate statistical methods and computer technology. Prepare a laboratory report containing a correct interpretation of results, calculation of uncertainties, error analysis, and discussion. As part of their laboratory work, students will be able to: Operate basic and advanced instruments (e.g., conductometer, polarimeter, tensiometer, viscometer, calorimeter). Assemble experimental apparatus for measuring phase equilibria, calorimetry, and electrolysis. Based on the measured data, students will be able to: Calculate key thermodynamic and kinetic parameters (e.g., dissociation constant of a weak acid, heat of dissolution). Construct and evaluate graphical dependencies, such as adsorption isotherms and temperature/concentration dependencies of viscosity and solubility. Construct and interpret the phase diagram of a three-component system (system of three liquids). Determine the rate constant of a chemical reaction based on kinetic data. Verify the validity of Faraday's laws based on experimental data from electrolysis. When discussing the results, the student will be able to: Evaluate the influence of external conditions (especially temperature and concentration) on the physicochemical properties of substances. Critically assess the sources of experimental errors and propose a procedure for refining the measurements. Interpret the physical significance of calculated constants and measured dependencies in the context of the behavior of real systems. Students of the education study program are able to: Explain and model abstract physical and chemical phenomena (e.g., surface tension, phase equilibria, adsorption) using analogies from everyday life in a way that is understandable to secondary and elementary school students as part of the didactic transformation of the field (KRAAU 1). Apply the principles of scientific and professional ethics when processing experimental data and demonstrate zero tolerance for falsification or distortion of results (KRAAU 6). Propose the organisation of work and classroom management in the school laboratory using measuring equipment (e.g., conductometer, calorimeter) to ensure the active involvement of students and the protection of equipment (KRAAU 3).
