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 .

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.

Molecular UV-Vis, IR spectroscopy: general principles. Lambert-Beer low and deviations from. Light sources. Monochromators. Detectors. Single and double bean spectrophotometers. Qualitative and quantitative analysis.

Atomic spectrometric methods.

Solvent extraction, distribution coefficient, distribution ratio, percent extracted.

Chromatography, principles of chromatographic separations. Classifications of chromatographic techniques. Theory of column efficiency in chromatography, selectivity.

Gas chromatography. Performing GC separations. GC columns, GC detectors, Stationary and mobile phases. Temperature selection. Quantitative measurements.

Bridging courses not required.

The student must show mastery of basic knowledge related to the equilibrium in aqueous solution and apply to all analytical techniques that rely on them as the gravimetric and volumetric analysis. It must also have the fundamental knowledge for understanding the most common instrumental analytical techniques (chromatography, spectroscopy).

- The student will have to show an understanding of the concepts and theories provided by the course; It must be able to propose the most suitable methods such or quantitative analysis of different types of samples .

- The student will demonstrate the ability to use knowledge and concepts that allow to reason according to the specific logic of the discipline. Must be able, in particular, to apply the theoretical knowledge acquired in specific laboratory practices.

-The student will have to show a 'proper skills to effectively communicate the knowledge acquired.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.

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
