The teaching is organized as follows:

Learning outcomes

The course provides the fundamental concepts of General Chemistry and some basics of Inorganic Chemistry. 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) will be illustrated and discussed. Concepts and methods for predicting qualitative and quantitative changes of intensive and extensive properties of evolving chemical systems will be also considered. Example cases for managing situations of chemical interest will be illustrated. The course involves the performance of some laboratory experiences to provide manual and critical skills in dealing with chemical analyses, as well as to provide basic knowledge on the common equipment of a chemical laboratory and how to work in safety.

Program

Theory:
Introduction. Chemical and physical properties of matter and their measurements.
Elements, atoms and compounds.
Nomenclature of inorganic compounds.
Chemical reactions. Reaction stoichiometry.
Ideal gases. Mention to real gases.
Thermochemistry. Internal energy and enthalpy. Standard enthalpy of reaction and formation.
Atomic structure. Atomic orbitals. Electronic configuration, Aufbau principle.
Periodic properties: atomic and ionic radii, ionization energy, electron affinity, electronegativity.
Elementary notions on the ionic bond. Ionic compounds.
Covalent bond. Lewis formula. Resonance. Molecular geometry and polarity. Orbital hybridisation. Single and multiple bonds.
Interparticle forces.
Properties of liquids. Solutions. Colligative properties.
Chemical kinetics. Arrhenius equation. Reaction mechanisms.
Chemical equilibrium. Equilibrium constant.
Acid-base equilibrium. Acid, base and salt solutions. Acid-base titration. Buffer solutions.
Solubility equilibrium.
Entropy. Spontaneous processes. Gibbs free energy. Standard free energy of reaction and formation.

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
Weak base-strong acid titration. Strong base-strong acid titration

Teaching modality:
The theory will be presented with the help of slides that will be projected on a screen and made available to the students on the Moodle platform. Example cases will be illustrated evidencing their salient points. Laboratory experiences will be delivered during the afternoon classes. Laboratory handouts will be made available to students on the Moodle platform. During the laboratory experiences, a tutor will allow be present to help students to perform the experiments, clarify the chemical concepts and process of the experience.

Examination Methods

The exam consists of a written test, including 18 questions on theory and 4 questions on stoichiometry exercises. All the 30 exercises are multiple choice questions. The exam is aimed at ascertaining the student's knowledge of the contents of the course. Particular attention will be given to the understanding of the concepts of general and inorganic chemistry.
For both attending and non-attending students the exam will focus on all the topics discussed during the theoretical part as well as on the part concerning laboratory experiences.
