Code: G290R-
Teacher:  Barbara Brunetti
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 6
Practices in laboratory:  1
Basic aims:  Providing a basic knowledge of the most important chemical principles in Analytical chemistry, especially concerning ionic equilibria in aqueous solution. Introducing the statistic/chemometric techniques necessary for processing the experimental data acquired in a laboratory of analytical chemistry Providing the practical information for operating in a chemical laboratory at didactic level.
Acquired skills:  The student will be able to calculate concentrations in solution from equilibrium constants by a systematic approach. The student will be able to use the basic statistical/chemometric techniques required for extracting/ elaborating / optimising the information collected by experimental measurements. The student will be able to practice the most basic laboratory operations.
Course contents:  Acid-base, precipitation, complexation and oxidation-reduction equilibria. Equilibrium calculations in aqueous solution by solving simultaneous equations. Theory and application of acid-base, precipitation and complexation titrations. Introduction to Electrochemistry. Electrodes and electrode potentials. Potentiometry. Errors in chemical analyses. Processing of analytical data (significance tests, calibration). Chemicals, glassware and analytical balances. Safety standards.
