Voltammetry experiment and study of the Ferri/Ferro cyanide system

Topics covered:

- Oxidation-reduction system

- Current-potential curve

- Electrochemical solvent inertial domain

Overvoltages - Study of a fast system.

Principles and objectives:

The aim of this lab is to plot the current-potential curves (i-f€) of the three solutions A, B, and C and to study the parameters that influence an electrochemical system.

Comments:

This Teaching Pack is used by the teacher in class, practical work, or supervised personal initiative work (TIPE).

It helps illustrate the concepts of the PC, PC*, MP, PSI, PT, and ExperimentC programs.

> Linear voltammetry curves in a few minutes.

> Observation of successive waves of oxidation-reduction.

> Highlighting of slow and fast systems.

> Observation of the diffusion plateau and the influence of agitation.

> Study of the electrochemical inertial domain, of accumulators.

> Going further in TIPE with corrosion studies.
