Lesson timetable

Learning outcomes

Module: Theory
The course provides the fundamental concepts of General Chemistry and some basics of Inorganic Chemistry. In particular:
- models and general concepts as means of justification and prediction of physical and chemical properties of systems of increasing degree of complexity: atoms, molecules, substances, multi-component systems (homogeneous and heterogeneous).
- concepts and methods for predicting qualitative and quantitative changes of intensive and extensive properties of evolving chemical systems.

Module: Laboratory
Numerical exercises complement and deepen the subjects addressed in the theoretical part. They are an essential tool for the student in order to improve the skill to solve real problems of chemical interest.
The experiments in the chemical laboratory complete the knowledge acquired in the theoretical and numerical exercises parts, facing the student with real problems of chemical interest. The student gain also information about the common equipment present in a chemical laboratory and how to work in safe conditions.

Module: Laboratory
Stoichiometry problems solving on the following subjects:
- Chemical formulas, chemical reactions and reaction stoichiometry.
- Ideal gas laws. Gas mixtures.
- Solutions: concentrations, colligative properties.
- Chemical equilibrium: applications of equilibrium constants to homogeneous and heterogeneous equilibria.
- Acid-base equilibria, buffers, acid-base titrations.

Laboratory experiments:
- determination of the hydrogen peroxide concentration in a commercial sample for pharmaceutical use
- determination of the number of water molecules in hydrate copper sulphate
- spectrophotometric determination of the concentration of a potassium permanganate solution
- weak base-strong acid titration
- strong base-strong acid titration
- determination of tap and commercial water hardness.

Assessment methods and criteria

The final exam consists of a written part, with solving of stoichiometry problems and general questions and of an oral part.
