Prerequisites

Contents

Laboratory Safety and Documentation · General rules for practical training and waste management · Laboratory book and reporting data Common Laboratory Equipment · Knowledge and use of the most important utils · Handling and cleaning glassware · Frequently used lab instruments Chemicals in the Laboratory · Handling with chemicals (solids, liquids, gases) · Transferring solids and liquids · Measuring mass and volume Dealing with Liquids · Pipetting a liquid (handling with several pipettes and buretes) · Preparing of solutions inclusive calculations Heating and Cooling of Chemicals · Heating divices and techniques · Cooling and techniques Methods of Separating · Separating a liquid or solution from a solid · Further important separation processes Chemical and Physical Properties · Color, smell · Solubility, density · Melting point, boiling point · Refractive index Synthesis and Identification of Compounds · Preparation of inorganic- and organic compounds · Characterization of compounds Water · Properties and interesting experiments · Some water analysis parameters UV Spectroscopy · Experimental basics of UV spectroscopy · Creating of a calibration curve · Spectrophotometric metal ion analysis

Learning outcomes

After participating in the module, the students will be able to handle chemicals/hazardous substances correctly and safely. The students will be introduced to the practices of a chemical laboratory and acquire knowledge and competences at working independently in this field. Upon completion of the module, the students will be familiar with basic chemical equipment/apparatuses and will know how to use them in a targeted manner. The students will learn about basic experimental techniques and related safety aspects. Furthermore, they will be able to do simple stoichiometric calculations. The students will be able to record and critically evaluate their experimental results and know how to apply the acquired knowledge to other problems. Within this module, students will form small groups and engage into productive teamwork. This practice will encourage the students to participate in, as well as create academic discussions, which will sharpen their communicative and social skills.

Assessment

Writing lab protocols for each topic and 4 tests (60 minutes) of knowledge during the semester (50 %) Written examination (60 minutes) at the end of the semester (50 %)

Remarks

No offer in Summer semester 2025! Good qualifications for subsequent modules with a chemical focus. For example the moduls: Sustainable Waste Management (11684) and Basic Soil Science (11645).
