After successful completion of the course, students are able to apply theoretical knowledge acquired in the basic lecture of physical chemistry in practical experiments, either independently or in groups, as well as to perform data analysis, evaluation and error analysis (standard deviation, outlier tests and error propagation) and to create measurement reports.

Practical course in Physical chemistry and physics

Practice examples from the chapters are given:

A. Ideal/real gases: 1. molar mass according to Dumas; 2. Joule-Thomson effect.

B. State changes: 1. critical point and vapour pressure determination; 2. boiling diagram; 3. melting diagram; 4. Cryoscopy.

C. Determination of thermodynamic parameters: 1st calorimeter: Precipitation and combustion reaction; 2. heat pump: Stirling engine, Peltier and Seebeck effect; 3. electrochemical cells and solar cells.

D. Physical and chemical equilibria: 1. adsorption; 2. surface tension; 3. acid-base equilibria; 4. distribution between two phases.

E. Kinetics: 1. cane sugar inversion (polarimeter); 2. ester saponification (conductivity or titration).

F. Transport phenomena: 1. diffusion; 2. measurement of the electrical conductivity of electrolyte solutions; 3. vacuum technique; 4. Viscosity.

G. Structure, quantum mechanics and natural constants: 1. dipole meter; 2. emission spectra of atoms; 3. photo effect; 4. Franck-Hertz experiment; 5. millikan experiment; 6. X-ray diffractometer.

Execution of individual exercises at different test stations:

e.g. Dipolemeter, vapor pressure apparatus, calorimeter, Kofler microscope, etc.

This includes the e.g. measurement of current and voltage, pressure, pH value, refractive index, viscosity, etc.

Data evaluation and writing protocolls

Execution of error analysis for the individual results obtained

A positive completion of the Physical Chemistry I course (165.003 or 165.098)) is required as an admission criterion. ATTENDANCE at the initial meeting of the LU is required.

If the number of enrollments exceeds the number of available laboratory spaces, thus necessitating a ranking of enrolled students with fulfilled entry requirements, the following ranking criteria will apply:

Ranking Criterion 1: Passed Mathematics for TCH I Exam (104.084).

(Date and grade of the exam is NOT a criterion).

Ranking criterion 2: Date of positive PCI exam (165.098)

Ranking criterion 3: Grade of PCI exam (165.098)

Ranking criterion 4: Date of mathematics for TCH I exam (104.084)

Ranking criterion 5: Grade of mathematics for TCH I exam (104.084)

You must successfully complete 10 exercises (it is not possible to skip exercises). Each exercise consists of: Preliminary discussion, execution, writing of minutes and debriefing. For each exercise there is a maximum of 10 points. (total number of points max. 100). The points for the partial exercises will be awarded according to the following scale: 2 points for preliminary discussion, 4 points for protocol, 4 points for debriefing + experiment execution. A sub-exercise is considered successfully passed if at least 5 points are achieved.

grading scheme

Very good:                  89 - 100

Good:                          77 - 88

Satisfactory:               64 - 76

Sufficient:                   51 - 63

Unsatisfactory:          0 – 50

• Protocol submission: 10 working days after completion of the exercise (working days = Mon-Fri; Sat, Sun and public holidays do not count)

• First protocol submission will be evaluated (caution: Points will be deducted if the protocol is faulty/inadequate , „Copy & Paste“ means 0 points). Only if the assistant approves the protocol, a debriefing can be made.

• The whole group is responsible for each protocol! If you have any questions about the protocol, please contact the respective assistant before the deadline

• During the course of the course a maximum of 2 negative performances may be achieved (partial exercises not accomplished). These must then be corrected by retries (new partial exercises).

• Only a maximum of 2 retries are possible. (In case of a self-caused retries there will be a 50% point reduction). If these 2 retries are not enough to complete the course, the course must be repeated.

• Attendance is compulsory for all members of a group until the end of the experiment. Failure to comply with the obligation to attend will result in the student being deprived of the day/part of the exercise and a retry must be made.

• If the protocol is submitted late, it will not be accepted and a retry must be made! Inadequate protocols or major misconduct (e.g. endangering others) in the laboratory can also lead to retries or exclusion of the course.

• In case of illness (doctors note, PCR-Test required) a limited amount of retries is avaliable.
