Learning unit contents

Theory

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. 

Supplement

Introduction to separation methods. We discuss the basic principles of chromatographic separation mechanism. We will detail the different parameters that characterize a chromatographic separation. We discuss the main types of chromatography: Gas chromatography Liquid chromatography Ionic chromatography Size exclusion chromatography

Learning outcomes of the learning unit

Theory

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.

Supplement

Understanding the basics in chromatography imply a perfect knowledge of separation mechanisms involved. The students will be able to select the adequate chromatographic technique including the selection of the stationary and mobile phases to separate molecules. They will also be able to understand the role that experimental parameters play on the efficiency of a chromatographic separation.

Prerequisite knowledge and skills

Theory

The course of general chemistry in 1st bachelor

Planned learning activities and teaching methods

Theory

See below

Practice

10 rehearsals are given after the theoritical course by C. Delvaux (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 geologists. 

Supplement

Two lessons (3h) given in December of the first quadrimester at 9 am till 12am. The course uses powerpoint presentations and exercices on the blackboard. An interruption of 15 minutes is provided at about the middle of each lesson. Directed works: Sessions are planned  for solving numerical problems in the course material. These sessions are very important because the final written exam is predominantly based on numerical exercises.

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

Theory

The course takes place every Friday morning at 8 am. The lessons (2h) are illustrated by several experimental demonstrations.

Recommended or required readings

Theory

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)

Supplement

The notes are available at the presses universitaires. The notes also include a list of numerical exercises, some solved.  As supplementary information, the consultation of the following work is recommended:
-CHIMIE ANALYTIQUE, Traduction de la 3ème édition américaine ci-dessus par Cl. Buess-Herman, J. Dauchot et T. Doneux (De Boeck - Université, Paris-Bruxelles, 2015)

Assessment methods and criteria

Theory

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.

Supplement

The exam consists in a written exam in January and September
