Introduction to the 2nd part of the course

We will meet on November 12th at 13:15 in person in the room GC G1 515. Duration until ca. 16:00.

Content:

- General Introduction and motivation for this part of the course by Prof. Christian Ludwig
- Introduction in how to perform the experiments and calculations
- Group formation for the second part of the course
- Expectations and reporting
- Safety

Handout will be available at noon on the same day.
Further supporting information will be provided during and after the course on this day (and later in the laboratory).

IMPORTANT and mandatory: Please watch the short video "Intro 6" (5:21 minutes) before you come to the course. It contains important safety information and information about how to perform the laboratory experiment:

According to information given by the assistants.

We meet in (GC C2 413) at 13:15pm.

Although, this last afternoon will not give you additional credits, it may be useful for you as an environmental engineer and will complement your understanding of the course content.

This last course helps the student to grasp the extensive possibilities which result from the experiments which have been performed in the laboratory.
Today we will implement relevant learnings from the experiments for obtaining a comprehensive understanding about systems containing complexing agents and dissolved toxic metal cations such as cadmium Cd(II).

The duration of the course will depend on the interest of the students. I expect that we finalize between 3 and 4pm.

Below you can download the GrFit software which will be used. However, to follow the course this is not needed.
