Training objectives

To acquire the basic theoretical knowledge on Analytical Chemistry, with special attention to chemical equilibria and volumetric methods of analysis. To learn the working principles of the most important analytical instruments of a chemistry lab and their applications.
To be able to manage, regarding the essential features, the basic equipment of a laboratory for analytical chemistry, such as glassware, burettes, automatic pipettes, pH meter and spectrophotometer.

Prerequisites

No specific prerequisites are required. However, OFA in Chemistry have to be overcome and a basic knowledge of General and Inorganic Chemistry, Physics, Mathematics can be very profitable.

Course programme

The analytical method; sampling and sample preparation; statistical analysis of results. (5 hours)
The equilibrium constant: definitions and calculations on solubility. (3 hours)
Acid-base equilibria: pH calculation on solutions of both weak, monoprotic acids/bases and buffers. (8 hours)
Volumetric methods: definitions, techniques and calculations. (2 hours)
Acid-base titrations: description and pH calculation in each point of the titration. (4 hours)
Argentometric, complexometric and redox titrations. (3 hours)
Galvanic cells, reduction standard potentials and the Nernst equation; measure and reference electrodes; the glass electrode. (5 hours)
Molecular absorption spectrophotometry: theory and instrumentation, the Lambert-Beer law. (5 hours)
Chromatography: theory, instrumentation and operating modes. (5 hours)
Atomic absorption and emission spectroscopies. (2 hours)
Description of lab experiences with projection of videos. (4 hours)
Numerical exercises in preparation for the exam (4 hours).

Didactic methods

Theoretical lessons (6 ECTS = 48 hours) with the help of the blackboard, videos and slide show on all the topics of the program.

Learning assessment procedures

The achievement of the 6 ECTS of the course of Analytical Chemistry requires to pass a multiple-choice test or an oral examination.
