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. <br /><br /> 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
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.<br /><br /> 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.

Planned learning activities and teaching methods
See below<br /><br /> 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 by G. Eppe and C. Malherbe (assistant) at the same place from 10:30 to 12:30.
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. <br /><br /> 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.

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.
9 written testing out of 10 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 6 highest notes out of the 9 are kept to calculate the mean and might lead to a bonus. A participation rate lower than 6 tests, does not give right to any bonus.
The distribution of the bonus for the exam is the following :
Criteria (mean value from 6 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
Examen en présentiel :
L'examen de Chimie Analytique I : Méthodes chimiques d'analyse est un examen à livre fermé qui sera composé de 2 parties: une partie (A) composées de questions courtes, et une partie (B) composés de questions ouvertes de résolution d'exercices.
La partie (A) durera 1 heure et comportera entre 15 et 20 questions de types QCM et de lecture de graphiques) balayant les notions théoriques des 4 chapitres du cours.
La partie (B) durera 3 heures et comportera 3 questions ouvertes longues de type exercices pouvant porter sur les 4 chapitres du cours. Notez que pour les ingénieurs chimistes, l'une des questions ouvertes portera sur les méthodes de séparation chromatographiques.
Lors de l'examen écrit en présentiel (4h), les étudiants seront invités à répondre aux deux parties (A) et (B) sur les questionnaires imprimés sur support papier.

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.

There is second session (August/September) if the note is strictly lower than 10/20.
