Learning outcomes

Master: Preparation reactions, simple and complex. Separation of reaction products (crystallization, filtration, distillation, extraction etc). Determination of the composition and properties of compounds. Purification of solids. The emphasis is directed towards methodically correct and safe process, leading to both qualitatively and quantitatively best results, and towards the ability to apply theoretical knowledge for explanation of the observed phenomena.
After completing the course, students will be able to: Apply occupational health and safety (OHS) rules in a chemical laboratory. Explain the theoretical principles of the reactions performed and describe them using correctly calculated chemical equations (precipitation, redox, acid-base, and complexation reactions). Present and discuss the principles of selected characterisation methods for inorganic compounds. Apply the concept of standard electrode potentials and the Beketov series of metals to predict the course of redox reactions. Accurately record and analyse the results of experiments. Communicate the results of scientific work clearly in oral, written, and electronic form. In the field of preparative chemistry, students will be able to: Perform basic and multi-step inorganic syntheses (e.g., preparation series of ferrous sulfate, preparation of copper oxide, synthesis of trihydrogenboric acid). Synthesise coordination compounds of transition metals (e.g., copper and cobalt amine complexes) and explain their formation. Apply advanced and unconventional methods to prepare modern inorganic materials and nanoparticles (e.g., cobalt ferrite via self-ignition and carbon quantum dots). Plan, design a procedure, and independently carry out the synthesis of a given inorganic compound based on a literature review. Based on experimental measurements, students will be able to: Determine the stoichiometric and physical parameters of substances (calculation of crystal water content, experimental determination of the relative atomic weight of zinc). Perform accurate volumetric determinations, including concentration calculations. Analyse the dependence of the chemical reaction rate on temperature and concentration of the starting materials. In the field of investigating the properties of substances, students will be able to: Classify and perform characteristic reactions of inorganic cations and anions. Identify unknown inorganic cations and anions in a sample based on systematic qualitative analysis and specific group reactions. Demonstrate the properties of selected gases and compounds. Students of the education study program are able to: Identify and evaluate specific safety risks when working with inorganic substances from a teacher's perspective (e.g., gas development, working with corrosive substances or heavy metal compounds) and propose specific preventive measures for a safe learning environment (KRAAU 3). Select and didactically transform university experiments (e.g., cyanotype, Beketov's series, ion detection reactions) into safe and feasible student tasks or effective demonstration experiments, taking into account the limited equipment available in schools (KRAAU 1). Provide and receive constructive formative feedback on manual dexterity, adherence to procedures, and quality of work during pair or group work in the laboratory (e.g., during syntheses and titrations), thereby training the skill of evaluating the practical work of future students (KRAAU 4 and 5).
