Training objectives
The course aims to provide students with an introduction to the language and methodology of study of chemical phenomena of a general nature. The course, both through frontal lessons and through exercises, intends to provide the student with knowledge to make her/him able to write the structure formulas of the main inorganic compounds and their nomenclature, to use the mole and the molar relationships in chemical reactions, to know the fundamental concepts of chemical thermodynamics for the study of the aggregation states of the matter, the solutions and the chemical balances with particular attention to the acid-base equilibria and precipitation, to know also the fundamental concepts of chemical kinetics. The knowledge of these concepts is fundamental to undertake the study of the successive courses that characterize the degree course.
Expected results
At the end of the course the student must show:
1) Knowledge and understanding: to know the fundamental principles of general chemistry to describe the matter and its properties: the atomic structure, the properties of the elements and their ability to form compounds, the molecular structures, the chemical reactions, energy exchanges, the states of matter, chemical kinetics, equilibrium in solution, acid-base properties;
2) ability to apply knowledge and understanding: having acquired application skills with reference to the balancing of reactions, stoichiometric calculations and problem solving on colligative properties, chemical equilibria, acid-bases reactions and on the solubility product;
3) Autonomy of judgement: to be able to independently evaluate and solve problems concerning the contents of the course;
4) Communicative skills: having developed a good oral and written communication capacity of the acquired concepts;
5) Learning skills: to be able to deepen the topics in different contexts and independently.
