Summary
In this chemistry module, students should be introduced to the different aspects of chemistry, all of which can assist them in interpreting and understanding chemical phenomena. The chemistry lessons covered during the first year of the integrated preparatory programme (abbreviated CPI in the French education system) are divided into three complementary modules: General chemistry, general chemistry practical work, and introduction to organic chemistry. This section of EXPERIMENTAL GENERAL CHEMISTRY (60 hours) describes the methods and experimental capacities for the first-year programme that the students must master at the end of the academic year. It specifies the knowledge and know-how that must be acquired in the field of measurement and the assessment of uncertainties. - A lecture covers safety in the laboratory: in this section the essential topics are covered before the start of the practical work, namely measurements and risk prevention in the chemistry laboratory. - The practical work sessions will consist of: ? One individual preparatory practical work session: handling precision glassware (volumetric pipette, burette, performing a dilution, washing the glassware, etc). ? Students work in pairs for the 14 rotating practical work sessions: The chemical practical work sessions are divided into six themes, bringing together the concepts discussed during the general chemistry course: pH-metric and conductometric doses; complexometry, precipitation and solubility; potentiometry/oxidation-reduction; kinetics; concept of thermodynamics.
Educational goals
The learning objectives for general chemistry practical work can be broken down as follows: - Know how to make the connection between practical work sessions and the concepts from the first-year integrated preparatory programme (CPI) courses; - Work in a chemistry laboratory while applying safety rules; - Learn how to work in a group, develop adaptability skills, progressively develop autonomy in the implementation of simple protocols associated with the quantification of the most frequently measured physical and chemical quantities; - Make distinctions between glassware instruments, select and use the appropriate equipment adapted to the level of precision required and use measuring devices (mass, pH, conductance, voltage, temperature, refractive index, absorbance, etc.); - Learn how to calculate uncertainty for experimental results; - Estimate uncertainty for experimental results; - Comment on experimental results; - Use a titration curve to determine the title of the dosed species; - Use a titration curve to determine an experimental value of a thermodynamic equilibrium constant ; - Learn how to manage chemical waste.
Sustainable development goals
Knowledge control procedures
Continuous Assessment
Comments: Assessment for general experimental chemistry:
- Continuous assessment (practical work reports and written in-class assessments at the start of practical work sessions);
- A final in-class exam that takes into account practice and theory.
Online resources
- Practical work reports available on Moodle can be printed out; - Videos available on Moodle on best practices regarding the handling of equipment in experimental chemistry: use of glassware, use of precision scales, performing a dilution, etc.
Pedagogy
- During four-hour practical work sessions students work in pairs (except for session 1 and during the exam); - Practical work carried out using a practical work handbook describing the experimental protocol; - Guided reports (documents to be completed). The emphasis is placed on the ability to use and discuss experimental results.
