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. Electrochemistry: galvanic cells, electrolysis, electrode potentials, Nernst equation.
