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.
This course contributes to the learning outcomes I.1, I.2, II.1, II.3, III.1, III.2, IV.2 of the MSc in chemical engineering.

Mode of delivery (face to face, distance learning, hybrid learning)
Face-to-face course
Additional information:
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 Hugo Muller (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.
Recommended or required readings
The course notes and the exercices book are available at the Presses Universitaires
Chimie Analytique I: Méthodes chimiques d'analyse 2021-2022, G. Eppe
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)
Exam(s) in session
Any session
- In-person
written exam ( open-ended questions )
Continuous assessment
Out-of-session test(s)
Additional information:
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
In-person, written exam
The evaluation consists of a written exam of maximum 4 hours in January on the whole subject. The exam is mainly based on solving exercises and direct applications of the principles seen in the course.
