Contribution of the course to the overall degree programme goals
The approach to the most relevant physico-chemical phenomena starts from a storical and/or descriptive point to obtain or present the mathematical expression of the Laws of Chemistry. Complementary is the teaching of stoichiometry (which is present only in this course) as the pratical and numerical calculation of the variabiles in real chemical systems or as the result of different analytical techniques.
The formative objectives of this part of the course are: 1) to develop the concept of chemical equilibrium and prove its importance for understanding chemical reactions; 2) introducing the energetics of chemical transformations (chemical thermodinamics) and its predictive abilities;3) to supply tools for describing acid-base equilibria, solubility and precipitation equilibria and electrochemical systems; 4) to help students to solve problems of stoichiometry that have to be regarded as applications of the theoretical part of the course.
In the choice or the subjects selected the indications of the Committee of the Italian Chemical Society for basic contents in Chemical Degree (Bologna, July 2007 meeting) has been followed.
Expected learning outcomes
A) To Know the quantitative laws that rule physical and chemical equilibria, and energy exchange in electrochemical systems.
B) To know the main features of acid-base equilibria, solubility and precipitation equilibria and electrochemical systems.
2. Ability to apply knowledge and comprehension:
A) To use the concept of chemical equilibrium to predict the results of exchange and redox reactions;
B) To be able to solve stoichiometric problems regarding the chemical equilibrium
3. Ability of judgment:
A) To be able to assess consistence of the results obtained with the application of chemistry laws both in theoretical field and analysis of experimental results.
B) To be able to recognize possible errors by a critical analysis of the applied procedure
4. Ability of exposition:
A) To be able to communicate acquired knowledge and the results of its application utilizing an appropriate terminology both orally and in written form.
B) To be able to interact with the docent and other students during the lesson.
5. Ability of learning:
A) To be able to take notes, selecting information in order of importance and priority
B) To be sufficiently autonomous in the resolution of stoichiometric problems.
