Travaux pratiques d'introduction à la chimie analytique [ WFARM1244 ]

general chemistry ; organic chemistry ; introduction to analytical chemistry

The teacher(s), helped by graduate students and technicians, will discuss the different types of particle exchange in a solution. The aim is first to give the practical basis that will help to understand the theoretical notions studied during WFARM1243 ; second to form the students to the analytical reasoning.  

At the end of the activity the student will be able to

• Behave in an analytical lab environment
• To understand notions such as 'trueness, accuracy, experimental error'
• To understand and use an experimental protocol
• To discuss the results he has obtained during the experiment

continuous evaluation based on the post-experiment reports, on the evaluation of the student preparation to the day's experiment, and a final exam.

the activity takes place in didactic labs

the actual experiments are preceded by theoretical  exercises (that need to be prepared by the student)  

• General aspects of an analytical lab ('good laboratory practices')
• Gravimetry and precipitometry
  • Quantification of sulfates and chlorides by several techniques, and quantification of iodide based on the European pharmacopoeia
• Acidimetry
  • Titrations in aqueous media
  • Titrations in non aqueous media
• Complexometry
  • Measure of the drinking water hardness
  • Screening for toxics (Bi ' Pb)
• Oxydimetry
  • Quantification of several ions (iron, iodides, calcium) and of pharmaceutical substances (chloramine T, sulfanilamide)
