There are no rules of prerequisites but it is useful to have basic notions of mathematics, (exponential notation, logarithms, equation of first and second degree).
Module B - Laboratory of Analytical Chemistry
The evaluation consists of a written test based on the solution of typical problems related to chemical analysis and an oral examination. The oral examination consists of a critical discussion of the written test and laboratory reports. The final vote is properly mediated between written, oral and laboratory reports.
The final grade is mediated between the results of the 1st and 2nd form.
Knowledge of the main laws of general chemistry and their application to solving problems of environmental interest.
Module B – Laboratory of Analytical Chemistry
Acquisition of
• Analytical Chemistry laboratory ability and introduction to theory and practice of modern instrumental analytical techniques.
• Field sampling ability, including pre-treatment and conservation of analytical samples
• judgment autonomy to evaluate and critically interpret, chemical and phyical-chemical experimental data according to analyzed environment.
• adequate skills in statistical treatment and evaluation of analytical data
• “on field” teamwork ability and evaluation of referenced data.
Atomic structure: general description, electronic structure of multielectron atoms, quantum numbers, orbitals. Periodic table of elements, periodic properties, ionization potential, electron affinity, electronegativity. Chemical bonding: ionic, covalent bond, octet rule, Lewis structures, molecular geometry (VSEPR teory), intermolecular bonds. Symbols, formulas and nomenclature. Moles, chemical reactions, concepts of thermodynamics. Chemical kinetics: basic concepts Balancing chemical equations, yield of reaction, stoichiometric calculations. States of matter: gaseous state (state equation, Dalton's law, vapor pressure and boiling temperature), solid state (relations between structure and properties), liquid (surface tension). Solutions: preparation, concentration. Chemical equilibrium: homogeneous and heterogeneous equilibrium, equilibrium constants, law of mass action, Le Chatelier principle. Equilibrium in aqueous solution: acids and bases, ionic product of water, pH, buffer solutions, salts hydrolysis. Titrations: acid-base. Equilibrium solubility, common ion effect.

Module B - Laboratory of Analytical Chemistry
Interdisciplinary approach will be follow, joining practical experiences (24 hours) with theoretical lessons (24 hours) and “on field” laboratory (24 hours). Field laboratory in lacustrine and montane environment will stress the sampling problems, the analytical approach on field, data elaboration and, finally, correct analytical report.
OFFICE HOURS
At the end of each lesson or in the studio of professor (Monday-Friday) by appointment agreed by e-mail or phone.
