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 perfect knowledge of the chemical reactions involved in solution, the notions of multiple equilibria and the influence of experimental parameters on the evolution of these reaction equilibria in solution.

Planned learning activities and teaching methods

See below

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 Hugo Muller (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.

 
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.

Out-of-session test(s)


Additional information:

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 in person, written exam :
The Analytical Chemistry I exam: The exam is a closed book exam consisting of open-ended exercise questions.
The exam consists of 3 to 4 open-ended exercise questions that may cover all 4 chapters of the course. Note that for chemical engineers, one of the open questions will be dedicated on chromatographic separation methods.
