Learning objectives
The goal of the course is to give the basic concepts for understanding the structure and properties of matter and the manner in which the substances may be transformed.
Expected learning outcomes
Students can acquire the language and basic knowledge necessary to his basic training which will be applied to advanced courses of chemistry.
Course syllabus and organization

Single session

Responsible
Lesson period
First semester
Lessons will be delivered online by the ZOOM platform. Lessons will be synchronous, according to the first semester timetable, but will also be registered. The instructions on how to access synchronous lessons and the registrations of the lessons will be available on the Ariel sites of the teacher. Consult this site often.
Course syllabus
General chemistry: Atoms and their structure. Quantum numbers and atomic orbitals. The periodic properties of the elements. Ionization potential and electronic affinity. The chemical bond. Ionic compounds. Covalent bond. Electronegativity. Hydrogen Bond. Hybrid orbitals. Molecular orbitals. The metallic bond. Shapes of molecules and Lewis formulas. The VSEPR model. Solid state. Crystal structures. Ideal gases. Solutions and dispersions. Vapour pressures of pure liquids and solutions, Raoult law. Distillation. Colligative properties. Thermochemistry and thermodynamics. Chemical kinetics. Activation energy. The catalysts. Arrhenius, Brønsted and Lewis acids and bases. Strengths of acids and bases. Ion-product of water and pH. Electrochemistry. Electrolytes and electric conductivity. Free energy and electric work. Galvanic cells and reduction potentials. The Nernst equation. Batteries and electrolysis. Coordination compounds. Inorganic chemistry of some elements (C, H, N).
Stoichiometry: Matter and measurements. Avogadro's number. The mole. Atomic and molecular weight. Chemical formulas. Weight composition of a chemical compound and of a mixture of compounds. Molar and ponderal relations in a reaction. How to balance a chemical equation. Limiting reactant. Yield of a chemical reaction. Solutions and concentrations. Ideal gases and relative laws. Chemical equilibrium: equilibrium constants, the effect of concentration, pressure and temperature variations. Ionic equilibria in aqueous solution: strong and weak electrolytes; neutral, acidic and basic solutions; pH and pOH; acids and bases, hydrolysis, buffer solutions, multiple equilibria. Complexometry. Precipitation equilibria: solubility and solubility-product constant. Effect of the presence of a common ion, of the pH, and of complexation on precipitation equilibria.
Prerequisites for admission
No preliminary knowledge is required
Teaching methods
Lessons and exercises will be made with the help of Powerpoint presentations. The files of these latter will be available on the Ariel site of the course.
Attendance to lessons is recommended.
Teaching Resources
Palmisano, Marcì, Costantini, Luciani, Schiavello "Elementi di Chimica" II ed., EdiSeS
Del Zotto "Esercizi di Chimica Generale", EdiSeS
Teacher's slides, available on the Ariel site of the course.
Assessment methods and Criteria
The learning will be verified by a three-hour written test on all the topics of the course. The test will be comprised of five open questions on general chemistry and three stoichiometry exercises. To sustain the test, the student will have to pass a pre-test consisting in fifteen multiple-choice questions on the basic and essential parts of the course.
The aim of the exam is to evaluate both the learning of chemical concepts, and the problem solving and reasoning skills of the student.
