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.
Execution of error analysis for the individual results obtained
Als Aufnahmekriterium wird das positive Zeugnis über die Vorlesung "Physikalische Chemie I" (165.003 bzw. 165.098)) verlangt. ANWESENHEITSPFLICHT bei der Vorbesprechung/Einführung zur LU.
Übersteigt die Zahl der Anmeldung die Zahl der verfügbaren Laborplätze und wird damit eine Reihung der angemeldeten Studierenden mit erfüllter Eingangsvoraussetzung notwendig, so gelten folgende Reihungskriterien:

(Datum und Note der Prüfung ist KEIN Kriterium)
Reihungskriterium 2: Datum der positiv abgelegten PCI Prüfung (165.098)
Reihungskriterium 3: Note der PCI Prüfung (165.098)
Reihungskriterium 4: Datum der Mathematik für TCH I Prüfung (104.084)
Reihungskriterium 5: Note der Mathematik für TCH I Prüfung (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 grade of the laboratory exercise is calculated from the total number of points of all exercises (see grading scale). The points for the partial exercises will be awarded according to the following scale: 3 points for preliminary discussion, 4 points for protocol, 3 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
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.
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.
Protocol submission: 10 working days after completion of the exercise (working days = Mon-Fri; Sat, Sun and public holidays do not count)
1.protocol submission will be evaluated (caution: Points will be deducted if the protocol is faulty/inadequate). Only if the assistant approves the protocol, a debriefing can be made.
The whole group is responsible for each protocol (group liability)! If you have any questions about the protocol, please contact the respective assistant before the deadline.
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.
Die Vorbesprechung Einführung in die PC Laborübung ist Aufnahmevoraussetzung (ohne Ausnahme)! Verspätung gilt als Nichterscheinen! Im Zuge der Vorbesprechung werden Sie weitere Einzelheiten erfahren.
The student must have at least 1 of the course(s) completed listed below:
