Content

The theoretical and practical parts cover the following topics:
•Laboratory Safety (Research on safety-relevant parameters using given examples)
•Qualitative Analysis: Wet chemical work, including separation processes, soda extract, and ion identification reactions
•Physical Chemistry: Calorimetric determination of solution enthalpy, Nernst equation, decomposition rate of a manganese complex, gas volumetry
•Documentation of Analytical Results
The following samples are conducted as part of the laboratory exercises:
•Sample 0: Laboratory plan
•Sample 1: Silver and calcium groups
•Sample 2: Iron and soluble groups
•Sample 3: Solid sample
•Sample 4: Calorimetry
•Sample 5: Electrode potentials (Nernst equation)
•Sample 6: Kinetics
•Sample 7: Gas volumetry
Previous knowledge expected

•NWNR100001: Introduction to Chemistry Lecture
•NWNR100002: Introduction to Chemistry Exercises
The essential content of the laboratory exercises is covered in the course NWNR100010 General and Physical Chemistry Lecture and is assumed knowledge for the laboratory exercises. Attendance of this course is strongly recommended as it makes studying for the lab test much easier.
Basic knowledge of Excel and statistics (e.g., mean, standard deviation, creating and labeling diagrams, etc.) is also required.
Objective (expected results of study and acquired competences)

After completing the course, students will be able to:
•Assess hazards (e.g., based on substance properties and database research) and reduce the risks associated with practical work through appropriate actions.
•Independently document experiments, carefully observe and interpret their results, manage their time effectively, and apply basic error analysis.
•Perform chemical separation steps relevant to process technology and analytics (e.g., precipitation and complexation) by separating inorganic element and molecular ions, describe the separation principles, and formulate the corresponding reaction equations.
•Conduct individual tests for separated ions and determine the qualitative composition of an unknown sample based on the results.
•Identify, interpret, and discuss interferences and other sources of error in the application of chemical separation processes based on the qualitative analysis procedure.
•Understand the complex coupled equilibria underlying the analyses and deliberately shift them by changing experimental conditions, as well as formulate the corresponding reaction equations.
•Determine thermodynamic quantities such as solution enthalpy using calorimetric methods.
•Perform procedures to verify fundamental electrochemical principles, such as the Nernst equation.
•Verify the rate laws of chemical reactions using spectroscopic methods.
•Measure gas volumes and apply the ideal gas law to determine the amount of a substance.
•Conduct safety-relevant database research for chemical substances, summarize and cite safety data sheets and general regulations, and interpret safety-relevant parameters such as MAC, BEL, LC50, and LD50 values.
•Apply safety measures, follow safety rules, recognize and use safety equipment, dispose of materials properly, and safely and competently use laboratory equipment such as Bunsen burners, water and sand baths, glassware, centrifuges, and other devices.
