Learning unit contents
The practical work is particularly based on teaching the use of weighing scales and laboratory glassware as well as basic analytical techniques such as iodometry, acidimetry, alkalimetry and complexometry, etc.
This will enable students to become familiar with working at a laboratory work bench and to acquire rigour and care. This work is carried out in a context of quality assurance. The practical sessions thus begin with the description of the laboratory glassware in order to familiarise students with concepts of quality assurance and statistics which all analysts require (concept of mistakes and number of significant figures).
During practical work, the construction of a calibration curve and measurement, during this interval, of unknown samples by means of an adequate use of the least squares regression model, are also planned.
Practical analysis work is organised into two teaching periods.
During the first period, the students carry out a series of handling procedures which are not marked and which enable them to familiarise themselves with the tools of analytical chemistry: learning to weigh, quantitatively transfer, take samples, write a complete, concise and critical report. On the basis of the percentage of errors determined during the physics-chemistry test, students analyse the quality of each stage of the handling procedures based on a list of questions on weight, transfer and sample-taking then recommence the handling procedure in order to improve their practice until they reach the required standards. During this time, students will also have the opportunity and supervision required to refresh or acquire basic theoretical concepts in order to productively carry out their marked practical work.
During the second period, students carry out dosing using acidimetric, manganimetric, complexometric, argentometric, iodometric, potentiometric, and spectrometric methods. This work is assessed in relation to the quality of the quantitative results obtained and the quality of the reports handed in. Assessment is completed through a series of five tests dealing with the pre-requisites and exercises directly related to the handling procedures conducted.
Learning outcomes of the learning unit
At the end of the second period, students should be able to carry out physical and chemical dosing procedures with normal margins of error using the methods practiced. They must also be able to write complete, exact, concise and well-argued reports.
Prerequisite knowledge and skills
Before tackling the practical work of analytical chemistry, students should have advanced knowledge of general chemistry. During the first two weeks, they can refresh this knowledge by reading the part of the analytical chemistry practical notes devoted to the prerequisites of analytical chemistry.
Planned learning activities and teaching methods
In analytical chemistry, supervised training of good analytical practices (filmed demonstrations and personal work at the laboratory bench), explanations of dosing procedures followed by the practical realisation of titrimetric and physical-chemistry handling procedures.
Mode of delivery (face-to-face ; distance-learning)
Given that the practical work of analytical chemistry aims to provide students with both manual (knowing how to manipulate correctly) and theoretical (knowing how to calculate and apply a result) skills, attendance at the different handling procedures is required.
Attendance during practical work is mandatory.
Recommended or required readings
- Pre-requisite for analytical chemistry. - Notes on practical work of analytical chemistry. - Introduction to analytical chemistry (CHIM0320-3).
Assessment methods and criteria
During the year :
- Marking of dosing procedures carried out according to the quality of the handling procedures, the quality of the performance and the quality of the compiled report. The quality of the handling procedures is estimated according to the error percentage added to an assessment framework adapted in accordance with the expected degree of precision for a particular analysis. A penalty system is applied in addition if the student does not respect the procedure or submits incomplete or erroneous reports.
- Assessment of theoretical knowledge through two tests direct relating to the pre-requisites and the practical handling procedures.
Exam :
- First session: students conduct a handling procedure chosen at random and are assessed according to the same criteria as during the year. Students receive specific operational methods containing neither equations nor explanations. The assessment framework and penalties are specific and specified at the appropriate time. The result of the exam counts for a quarter of the final mark with the tests also counting for a quarter and the results of the handling procedures for the year making up the remaining half.
- Second session: students conduct a random handling procedure and are assessed according to the same criteria as during the year. Student receives specific operational methods at the start of the exam containing neither equations nor explanations. The assessment frameworks and penalties are identical to those of the first session. In all cases, students are confronted with resolving a similar problem to those proposed during the year (tests). In the final mark, the above problem counts for a quarter and the result of the handling procedure counts for the remaining three-quarters.
Reminder :
Attendance at practical work is mandatory. Consequently, in conformity with article 6 of the general exam rules, a level of absenteeism that is too high may result in the student being prohibited from taking the exam..

Organizational remarks
There is a forum on "MyULg" (section: Studies-Courses) where students can ask questions about the subject.
Notes on the practical work as well as the pre-requisites for the practical work for analytical chemistry are also available via "MyULg".
