The aim of the course is to provide a basic understanding of principles, instrumentation and applications of chemical analysis.

The laboratory exercises will allow the acquisition of the fundamental theoretical and methodological principles for operating in a chemical analysis laboratory: safety, knowledge of the instruments, preparation of solutions, knowledge of chemical balances in aqueous solution, methodologies for the quantitative determination of inorganic substances .

Review of the notions of basic stoichiometry, nomenclature and balancing of each type of chemical reaction. Expression of the concentration of solutions according to the most common physical and chemical units.

Data handling and spreadsheets. Accuracy and Precision, determinate errors, indeterminate errors. Ways of expressing accuracy and precision.

General concepts of chemical equilibrium in water solutions. Activity and activity coefficients. Thermodynamic equilibrium constant and activity coefficients, the diverse ion effect. Acid-base theories, acid-base equilibria in water, the pH scale. Weak acids and bases. Buffers. Precipitation equilibria, the solubility product. The diverse species in solution on solubility. Complexes and formation constants Chelating agents and chelates. Redox equilibria. Electrochemical cells. Nernst equation. Electrode potential

Systematic approach to equilibrium. Mass balance equations, charge balance equations.

Acid-base titrations. Precipitation titrations. Complexometric titrations. Redox titrations.

Bridging courses not required.

D1- Knowledge and understanding. The student must acquire mastery of the basic knowledge relating to equilibria in aqueous solution and apply them to all analytical techniques based on them such as gravimetric and volumetric analysis. He/she must also possess the fundamental knowledge for understanding the most common instrumental analytical techniques (chromatography, spectroscopy). The student must learn the main safety rules, the functioning of the instruments, equilibria in solution and classical quantitative chemical analytical techniques.

D2- Ability to apply knowledge and understanding. The student must demonstrate the ability to use the principles of analytical chemistry provided by the course; he/she must be able to propose the most suitable qualitative or quantitative methods for the analysis of different types of samples. The student must demonstrate the ability to use chemical equilibria in aqueous solution and the use of equilibria shifts to achieve specific objectives (use of chemical indicators, solubility variation, fractional precipitation, masking of ionic species in solution, etc.).

D3- Autonomy of judgment. The student must demonstrate the ability to use knowledge and concepts that allow them to solve specific analytical problems. In particular, they must be able to apply the theoretical knowledge acquired to specific laboratory practices.

D4- Communication skills. The student must demonstrate an adequate ability to effectively communicate the knowledge acquired with appropriate terminology and appropriate examples. They must demonstrate that they have developed communication skills suitable for the presentation of the data obtained during practical experiences, the calculations performed and the final result using appropriate specific terminology. The ability to present their results in both analytical and synthetic form.

D5- Learning skills. The student must be able to build his scientific growth path in a critical and autonomous way, correctly using the study material provided by the teacher and the in-depth material that he himself can obtain. He must also demonstrate that he can act appropriately and autonomously within a chemical laboratory.

Assessment

Subject to approval of the practical laboratory part, the learning assessment includes:

- Written Test (solving advanced stoichiometry exercises and answering open questions on topics covered during the course); 2 hours. The oral test is accessed only if the result of the written test is at least 18/30.

- Oral Test (oral discussion on the topics covered during the course).

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.

Teaching

Students not attending theoretical lessons are invited to contact the teacher and consult the Moodle platform where all the material used during the lectures will be available

Attendance

Attending lectures is not mandatory, but highly recommended.

Attendance at laboratory exercises is mandatory.
