This optional extension to the LU Orientation course for the beginners in Technical Chemistry I (LVA-Nr. 163.173) is part of the measures according to a quality management in the beginning phase of study to support the student's self-orientation.

The practical exercises take place on the following day after the LU Orientation course for the beginners in Technical Chemistry I (LVA-Nr. 163.173), i.e. on 3rd October 2018.

Certificates are issued together with the LU Orientation course for the beginners in Technical Chemistry I (LVA-Nr. 163.173) only after participation in a second run of the E-ChemTest at the end of the summer term 2019 (last week in June 2019, details will be announced).

To give a rough overview of the band-width of the bacchelor study "Technische Chemie" the students will attend 1 further day (as optional extension to LU Orientation course for the beginners in Technical Chemistry I) 8 hours lab exercises in hands-on experimental work under intense supervision of tutors and assistents. The exercises comprise of those experiments in synthetic chemistry, analytical chemistry, physical chemistry and biochemistry, which have not yet been done the previous day.

The participation at the practical exercises on 3. October 2018 is only allowed for the participants of the E-ChemTest!

The 4 topics of the lab course of the will cover the following exercises: 1) synthetic chemistry (synthesis of an azo-dye, performance of a polyamide condensation, esterification) 2) analytical chemistry (characterisation of wine: titration of the total acid content, photometric measurement of the tartaric acid content, thin-layer-chromatography of wine dyes, atomic absorption spectroscopy of the copper content of wine) 3) physical chemistry (determination of the osmotic pressure of sacharose solutions) 4) biochemistry (DNA isolation from E. coli cells and an introduction into methods of bioengineering)

Confirmation of participation in the course examination comprises of personal participation and active class participation and hands-on experimental work on 3. October 2018. The certificate will be issued together with the LU Orientation course for the beginners in Technical Chemistry I only after participation at a second run of the E-ChemTest at the end of the following summer term.

The practical exercises take place on 3.10. between 09:00 - 13:00 and 14:00 - 18:00 in the following students labs: Synthetic chemistry: students lab BK U1, Physical chemistry: students lab BC O4 H31, Analytical chemistry: students lab BB 05 C01 and C17, Biochemistry: students lab BC O4 H01/H11. For the practical exercises at 3. October 2018 in the labs bring the following items: 1) a white lab coat (compulsary) 2) paper tissue, dish washing detergent, waterresistant ink writer, lighter (recommended); latex gloves

For the exercise in physical chemistry you will need a pocket calculator!
