Assessment Methods

Verification of learning:

The final exam consists of a written test and an oral test. During the course, three written assessment tests will be held, which may give exemption from the final written test.

Teaching period

First semester

Objectives

The course aims to provide knowledge on the electronic structure of atoms and molecules and the correlations between molecular structure and macroscopic properties of substances. It also defines the general principles of thermodynamics of chemical reactions such as acid-base reactions and redox reactions. An integral part of the course are the numerical exercises that allow the student to determine for example the amount of products generated in the different chemical reactions, the composition of the solutions, the pH value.

Contents

Matter. Pure substances and mixtures. Structure of the atom. Relative atomic masses.
The concept of mole and the Avogadro constant. Chemical reactions and stoichiometry. Limiting reagent. Chemical formulas. Nomenclature of the principal chemical compounds. The Periodic Table. The ionic and covalent bond. Electronic configuration of atoms. VSEPR theory. The balancing of redox reactions. The gaseous state. The liquid state. Changes of state. The hydrogen bonding. Solutions. Colligative properties. Chemical thermodynamic. Chemical kinetic. The chemical equilibrium. Acid-base equilibria. Ionic product of water, pH of solutions, hydrolysis. Buffer solutions.

Teaching Methods

During the lectures will be held, at the blackboard, several exercises on various topics, such as the calculation of the limiting reagent, pH calculation of the solutions ecc. In the classroom, students will be shown some reactions that involve color change or formation of a precipitate. The course also has 1 CFU (12 h) of laboratory dedicated to titration of a strong acid with a strong base and to the different behavior of two hydroxides one amphoteric and the other one not.
