Gauthier Eppe

Language(s) of instruction

French language

Organisation and examination

Teaching in the first semester, review in January

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The balanced reactions (acid-bases, redox, complexation, precipitation) are treated in terms of exchange of particles between donors and acceptors, thus unifying the concepts used in the study of the various reactions in aqueous solution. The next step consists in establishing a relationship between the variations of the conditional constants (acidity constants, formation constants of complex, normal potentials, exchange and partition constants) and the conditions of the medium (pH, ionic strength, complexing agent). These concepts being acquired, the implementation and the quantitative application of these various reactions with the purpose of analysis (titrimetry and gravimetry, primarily) are considered while insisting on accuracy which one should expect. 

Learning outcomes of the learning unit

To understand, interpret and apply the various reaction steps of an analysis protocol in order to obtain the best performances in terms of accuracy and precision. They are the major objectives of the course. This implies a good knowledge of the chemical reactions which it implements.

Prerequisite knowledge and skills

The course of general chemistry in 1st bachelor

Planned learning activities and teaching methods

See below

Mode of delivery (face-to-face ; distance-learning)

The 10 courses take place every Friday morning. The lessons (1h45min) are illustrated by several experimental demonstrations.
The last 3 courses anre dedicated  to rehearsals. They are given by C. Kune (assistant)
These rehearsals illustrate the course and contribute to its understanding thanks to a series of problems and exercises on the various chapters, while insisting particularly on acid-base and complexometric titrations, Redox and Pourbaix diagrams which are of primary importance for students in geology. 

Recommended or required readings

The course notes are available at the Presses Universitaires.
A copy of the powerpoint slides are also available.
As supplementary information, the consultation of the following works is recommended: - ETUDE ANALYTIQUE DES REACTIONS CHIMIQUES DANS L'EAU by J.Y. GAL (TEC et DOC-LAVOISIER, Paris 1989) - ANALYTICAL CHEMISTRY by D.A.SKOOG, D.M. WEST and F.J HOLLER. 3rd Edition (2015)

Assessment methods and criteria

The evaluation consists in a 4h written examination in January covering all topics mainly focused on exercises and direct applications of the principle seen during the lectures. 
There is second session (August/September) if the note is strictly lower than 10/20.
