Procedures in chemical laboratories
vary slightly according to the specializations but are basically the same for all the
students
Year 1: 3 lessons per week
basic work with glass, cork and rubber, preparation of solutions, determination of boiling
and melting points, weighing, density measurement, crystallisation, sublimation,
distillation, microcrystalloscopy, preparation of gases and their proof, photochemical
reactions, reactions of metals, flame test
Year 2: 4 lessons in two weeks
preparation of organic compounds, organic qualitative analysis, dissolution, heating,
cooling, stirring, drying, purifying, sublimation, distillation, extraction
Year 3: 4 lessons per week
Analytical chemistry: volumetric solution, titration, indicator, volumetric analysis,
alkalimetry, acidimetry, manganometry, iodometry, chelatometry
Basics of chemical engineering: grinding, hydrostatics, filtration, sedimentation, stirring,
Year 4: 8 lessons a week
analytical chemistry- potentiometric / conductometric / coulometric titration
spectrophotometry, chromatography, polarimetry, refractometry
viscosity, density, reaction kinetics, polarography, electrophoresis, flame photometry,
cryoscopy
spectrophotometry
heat exchanger, electrolysis, adsorption, calorimetry, differential distillation, azeotropic
rectification
chemical tests – e.g. determination of sulfur dioxide in wine, determination of ammonium
ions in water, determination of salt contents in foods, analysis of mineral waters
