Classical Chemical Analysis (ANA-I) - Basic definition and principles Fundamental laws and formulas, qualitative vs. quantitative analysis. - Chemical Reactions Types and variants: Neutralisation, precipitation of sparingly soluble and insoluble salts, complexation and chelating, reactions releasing gases, markedly coloured soluble products and precipitates. - Qualitative analysis ... Definition and principles; Identification of inorganic ions: (i) selected cations: Ag+, Pb2+, Cu2+, Fe2+/3+, Co2+, Ni2+, Cr3+, Ca2+, Na+, K+, and NH4+; (ii) selected anions: Cl-, I-; SO42.-, SO32-; HPO42-, CO32-; CrO42-, MnO4-; NO2-, NO3-. - Quantitative Analysis / Gravimetry (Precise weighing) Definition and basic principles, laboratory operations to obtain, isolate, and manipulate the precipitates, weighing procedure(s). Selected methods of gravimetric determinations: silver as AgCl, iron as Fe2O3, and nickel as Ni(DMG)2. - Quantitative Analysis / Volumetry (Titrations) Definition: Basic principles, way of indication, standardised solutions, titration curves and equivalence point(s). (i) Acid-base (protolytic) titrations: Main principles with chemical equations, indicators and their colour changes, types of titration curves (according to the titrant); (ii) Precipitation titrations: Main chemical equations, indicators and their colour and/or phase changes, typical titration curve, selected example(s) from analytical practice. (iii) Complex-forming titrations: Main chemical equations, indicators and their colour changes, typical titration curve, selected example(s). (iv) Redox titrations: Main chemical equations, indicators and their colour changes, typical titration curve, selected examples. - Basic Calculations in Chemical Analysis Concentration and the content: definition, molar concentration, mass concentration, percentage, recalculations; Calculations of pH: strong and weak acids and/or bases, mixtures of two acids, salts from acids and bases.

Introducing students to the elements of classical chemical analysis, namely: (i) basic concepts and definitions, qualitative vs. quantitative analysis, basic laboratory operations; (ii) reactions and identification of selected inorganic cations and anions; (iii) gravimetric analysis: principles, laboratory equipment and selected methods, (iv) volumetric analysis: principles, laboratory equipment and selected methods; (v) basic calculations and recalculations: concentration vs. content, calculating stoichiometry, pH for solutions of acids, bases, and salts.
Graduates of the course will gain a basic overview on classical chemical analysis and its key topics, will also practice working with chemical literature and improve their scientific English.
