Evaluation of thermal stability of compounds: thermal decomposition of CaCO3, eggshell, and PbO2.

1 CFU (12 hours): characterization of samples obtained from laboratory experiments by: elemental analysis with subsequent determination of experimental formula for Ca(C6H8O8)x2H2O, Cu(CH3COO)2xH2O, Al(C5H7O2)3, Cr(C5H7O2)3, Fe(C5H7O2)3, IR spectroscopy for Ca(C6H8O8)x2H2O, Cu(CH3COO)2xH2O, Al(C5H7O2)3, Cr(C5H7O2)3, Fe(C5H7O2)3 , UV-VIS spectroscopy for Al2O3-Cr2O3, CoAl2O4, Cu(CH3COO)2x H2O, Cr(C5H7O2)3, Fe(C5H7O2)3, and magnetic moment measurements for Cu(CH3COO)2H2O, Cr(C5H7O2)3, Fe(C5H7O2)3

Teaching methods

Lectures (theory and exercises) conducted through Power Point presentations. Practical laboratory exercises conducted by operating in small groups. It is mandatory to attend 75% of the practical exercises, lower values do not allow to obtain the signature of attendance and registration for the examination call.

Assessment methods

Verification of learning is based on an oral test, evaluation of laboratory activities and laboratory reports. Four questions are typically proposed on: - general topics (periodic properties, maximum packing theory, crystal systems and Bravais lattices, cohesion energy, crystal field theory, magnetism, properties of simple compounds); - topics related to the characteristics and properties of the elements and compounds of the major groups (descriptive inorganic) - topics related to the characteristics and properties of transition metals and their compounds - laboratory activities, including stoichiometric calculations related to them. Oral (70 %), laboratory reports (20 %) and activity performed in the laboratory (10 %) will contribute to the final grade (thirtieths). Specifically: oral: evaluation of language property, scientific correctness, clarity, level of thoroughness laboratory reports: assessment of clarity, organization of data, correct interpretation of data activity performed in laboratories: assessment of manual dexterity, correct use of equipment, instrumentation, personal protective equipment, and ability to work in an orderly manner
