Analytical chemistry I
Syllabus
Part 1
Propedaeutic concepts Analytical Chemistry: definition, history, significance. Analytical methods. Sequence of steps in a typical quantitative analysis. Sampling. Elements of theory of errors applied to analytical chemistry; criteria for data treatment and statistical tests. Concentration scales, ionic strength, activities, activity coefficients. Nernst law, galvanic cells, ion-reversible electrodes, electrode potential scale.

Part 2
Volumetric analysis. Titration methods: definitions, classification, standards. Acid/base, precipitation, complessation and redox titrations: mathematical descriptions of the corresponding equilibria and titration diagrams; in particular, De Levie method for easy unapproximated simulation of acid/base equilibria and titration curves even in very complex cases; examples of spreadsheet implementation; survey of experimental cases.

Part 3
Electroanalysis. Conductimetry, potentiometry (ion-selective electrodes, pH-metry, p-Ionometry, redox potential, water hardness), voltammetry (cyclic voltammetry, polarography, pulsed techniques, stripping techniques for trace analysis), amperometry (trace water by Karl Fischer method, dissolved oxygen by Clark method), biosensors and electronic tongues/noses (hints). Fundamentals, instrumentation, protocols (standardization, direct measurements, instrumental titrations). Model cases in the analytical laboratory and in fundamental and applied research.
