Learning Objectives
Learning Objectives - Lectures
Acquired knowledge:
The course deals with the general basis of analytical chemistry in order to understand the mechanisms, the errors and the problems connected with the classical volumetric quantitative analysis. The principal instrumental methods (optical and electrochemical methods, mass spectrometry, separation techniques, such as chromatography) are discussed.
Acquisition of expertise in analytical chemistry. Ability to design and carry out an analytical procedure from the sampling step, the choice of the instrumental analysis, to the statistical evaluation of the analytical data.
Learning Objectives – Laboratory exercises
Knowledge: Systematic treatment of chemical equilibria. Classical volumetric quantitative analysis. Potentiometric measurement and pH evaluation. Data analysis.
Ability to apply knowledge and understanding:
Develop critical, quantitative thinking.

Type of Assessment
Lectures and laboratory exercises
The evaluation procedure will be carried out through an oral examination usually involving:
- stoichiometric exercises on equilibria in solution and on the concentration of a solution;
- open-ended questions on the correct reporting of analytical data (aimed at verifying the ability to apply knowledge and understanding, the critical thinking skills, the autonomy of judgment, the effectiveness of the learning methods)
- volumetric analysis and instrumental analysis (aimed at verifying the oral communication skills, the ability in the use of a specialized scientific language).
