Annotation -
In the first five lectures the students are familiarized with the fundamentals of electrochemistry as a specific approach to investigation of redox reactions at the electrode from thermodynamic, kinetic and mechanistic point of view. At that occasion important concepts, relationships and contexts will be clarified. In the second part the detailed overview of all main electrochemical techniques and electroanalytical methods will follow together with explanation of their principle and with description of their application possibilities in various areas of chemistry. Qualitative evaluation of the obtained data and the interpretation of results is also an important part of the course.

Aim of the course -

Students will be able to:

  • understand the fundamental principles of electrochemical and electroanalytical methods
  • gain knowledge of their possibilities and applications in various branches of chemistry (org., inorg., phys., anal., theor., biochem.,...).
  • based on the theoretical backgrounds, the students will be able to to master experiments, to control instrumentation, to acquire esxperimental data and to make the first interpretation.
