Catalogo dei Corsi di studio

Analytical Chemistry addresses the fundamental aspects of acqueous solution equilibria. The course of Analytical Chemistry has the objective of providing both the basic principles of equilibrium in aqueous environment, and of the most widespread instrumental chemical analysis techniques. Specific training objectives are: the knowledge of equilibria in solution; the calculation of the pH and of the concentrations of a system at equilibrium (spontaneous or induced), the use of the buffer solutions, the knowledge of the theory of the most common techniques of chemical instrumental analysis.
The knowledge and skills acquired in this course will constitute a fundamental aid in subsequent studies focused on biotechnological applications.

Students who have passed the exam will be able to know and understand (acquired knowledge)

- the meaning of equilibrium;
- the calculation of the pH in aqueous solutions;
- the usefulness of buffer solutions;
- spectroscopic techniques;
- chromatographic techniques;
- mass spectrometry;
- the criteria for choosing instrumental analyses.


Students who have passed the exam will be able to (acquired skills):
- calculate the pH of a solution;
- prepare and use a buffer solution;
- select the best analytical technique according to the sample to be analyzed;
