Learning outcomes
After completing the course, students will be able: a) to describe the application area and basics of the voltammetric methods, b) to explain the functioning of the potentiostat and major processes and chemical reactions involved in a voltammetric measurement, c) to prepare a solution and run measurements of organic molecules in aqueous and non-aqueous solutions, d) determine the redox potentials of electrochemically (pseudo) reversible reactions and relate them to energies of the molecule HOMO and LUMO.
