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, hybrid learning)
The course takes place every Friday morning from 8:15 to 10:15 am. The lessons are illustrated by several experimental demonstrations adn exercices. The rehearsals are given after the theoritical course from 10:30 to 12:30 or during the afternoon by A. Verdin (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.
The sudents are invited to work by group max 3 to 4 on series of exercices proposed and posted on e-campus. The students are free to prepare in advance the rehearsals The corrections are done at together at the black board.
Organisational adjustments related to the current health context
Recommended or required readings
The course notes and the exercices book 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
Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.
6 written testing are planned during the TD. The test is related on the subject developed during the previous course. 30 minutes are foreseen for the test at the beginning of the TD. The 4 highest notes out of the 6 are kept to calculate the mean and might lead to a bonus. A participation rate lower than 4 tests, does not give right to any bonus.
The distribution of the bonus for the exam is the following :
Criteria (mean value from 4 best tests)
Mean < 12/20 Bonus +0
12<= Mean < 14/20. Bonus +1
14<=Mean < 16/20 Bonus +2
16<= Mean < 18/20 Bonus +3
18<= Mean < 20/20 Bonus +4
En présentiel
L'évaluation consiste en un examen écrit de 4h en janvier sur l'ensemble de la matière. L'examen est principalement basé sur la résolution d'exercices et d'applications directes des principes vus au cours.
Modalité d'évaluation en distanciel :
L'évaluation consiste en un examen écrit de 4h en janvier sur l'ensemble de la matière. L'examen se constitue de 4 questions ouvertes sur les principaux chapitres du cours (réactions acide-base, réactions de complexation, réactions d'oxydoréduction). L'énoncé de l'examen sera disponible via eCampus pour la durée de l'examen uniquement et les résolutions devront être envoyées par les étudiants via photo/scanner dans un délai prédéfini après la fin de l'examen. Un non-respect de ce délai peut entraîner une annulation de l'examen.
Une surveillance via une plateforme vidéo (Blackboard, lifesize, autre) sera mise en place durant toute la durée de l'examen. Durant cette période, la caméra ainsi que le micro des étudiants devront rester allumés.
