Learning objectives
The aim of the teaching is to provide a knowledge of basic chemistry, preparatory to the subsequent teachings of Organic Chemistry and Biological Chemistry. More specifically, the teaching will provide the minimum tools necessary for understanding the chemical language and basic topics (atoms, chemical bonds, chemical reactions, chemical, thermodynamic and electrochemical equilibrium). This basic knowledge constitutes the necessary tools for understanding the chemical language of life, an indispensable element for the future biological studies.
Expected learning outcomes
At the end of the teaching, the student will have to reach skills relating to the structure of matter and chemical bonds. The concepts learned will guide the graduate to work competently in all phases of the experimental and analytical management of chemical processes. In particular, the basic concepts of nomenclature, chemical formulas and stoichiometry, and the concepts concerning solutions, dissociations in solution, chemical and electrochemical equilibria, pH and buffer solutions must be applied.
