General and inorganic chemistry

A.Y. 2021/2022
Overall hours
Learning objectives
The objective of this course is to give students the basic concepts for understanding the structure and properties of Matter and the way elements and compounds combines to yield new compounds. In particular I propose two units:
Unit 1 - knowledge about atomic structure, chemical bonding, chemical reactions using balanced chemical equations, quantitative study of reactants and products with mole method and limiting reagent.
Unit 2 - Knowledge about aqueous solutions: weak acid and weak bases and their ionization constants, buffer solutions, acid-base titrations, salt hydrolysis and redox reactions.
Expected learning outcomes
Students will acquire the language and basic knowledge necessary to their training. The course provides the students with an important background to understand the molecular basis of their following studies.
Unit 1 - Students would be able to name substances using IUPAC nomenclature, to draw molecular structures and to determine the molecular geometry of inorganic compounds, to balance chemical equations and to calculate the yield of processes by mole method.
Unit 2 - Students would be able to calculate the pH of different aqueous solution. Students would be able to balance redox reactions using the half-reaction method and to calculate the voltage in a galvanic cell using Nerst equation.
Course syllabus and organization

Single session

Lesson period
First semester
The lectures will be carried out partly in person and partly online (using the Microsoft Teams platform), according to the published calendar and the indications
given by the University. The lessons will be recorded and made available on the Ariel website. The exercises aimed at preparing the exam will take place online, partly asynchronously (providing the material on the Ariel website) and partly with synchronous mode to give the student the opportunity to propose exercises to be solved together with the intent of clarify any doubts (through the Microsoft Teams platform). The laboratory exercises will be carried out regularly in the presence, scrupulously following the rules set by the University and those who cannot be present will be able to follow the development of the experiment in synchrony through the Microsoft Teams platform.
Information on the organization of lessons and how to access Microsoft Teams and any other information on teaching will be available on the ARIEL website
teaching: it is therefore recommended to consult it regularly. Based on the evolution of the epidemic and in compliance with the relevant regulations, they will be able to
modify the modalities of the activities planned in the classroom, informing the students through ARIEL. The course program will not change. The exam methods will consist of a written and an oral one through the Microsoft Teams platform.
Course syllabus
Inorganic compounds nomenclature; oxides, anhydrides, hydroxides, salts, hydrides, oxyacids. The atom structure and properties. Periodic table: properties
Electronic configurations, Structure of inorganic compounds, hybridization and molecular geometries. Intramolecular chemical bonds: covalent bonds, dative bond and ionic bond.
Intermolecular bonds: Van der Wals, London and hydrogen bond
Mole and Avogadro number
Chemical reactions: balance, stoichiometric calculations, limiting reagent
Aqueous solutions: molarity of a solution, dilutions
Chemical equilibrium - Le Chatelier principle - calculation of the constant by means of equilibrium concentrations (Kc). Strong acids-strong bases, weak acids-weak bases
The ionic product of the water-pH scale. PH indicators
Buffer solutions. Hydrolysis reaction. Acid-base titrations
The enthalpy and the spontaneity of a process
Oxidation states and oxidation-reduction reactions: balancing of equations with the half-reactions method.
Redox potentials. Nernst equation and galvanic cells
Prerequisites for admission
Being a basic course, there are no prerequisites other than the knowledge acquired during high school.
Teaching methods
Lectures, exercises and slides projection in classroom and the use of the Kahoot program on tablets or smartphones. Before each ongoing test, a simulation will be performed in the classroom through the resolution of exercises by the teacher
Teaching Resources
Text book: J.C. Kotz, P.M. Treichel, J.R. Townsend "Chimica" V Edition, EdiSES. Notes from lessons, textes and solutions of exam texts are available at
Alternatively we recommend the use of any other general chemistry text as long as it is university
Assessment methods and Criteria
During the General and Inorganic Chemistry course, two written tests are scheduled; the first will take place halfway through the course, the second, the first week after the end of the course. Only students who have passed the first test with a mark greater than or equal to 18 can access the second test. To pass the exam, both tests must be sufficient, i.e. each passed with a mark greater than or equal to 18. The final mark will consist of the mathematics average of the two marks obtained in each ongoing test. Oral interview is not carried out. The ongoing tests are not mandatory and require registration. The typology of exam tasks consists of a variable number of exercises according to the examples shown during the classroom exercises. For those who do not pass the ongoing tests and for those who decide a priori not to participate, the exam will consist of a single written test on the dates set within each exam session. The single test will consist of a variable number of exercises on the entire program.
Practicals: 24 hours
Lessons: 36 hours
