Short course annotation in English

Students will obtain: 1) knowledge on the theoretical backgrounds of analytical chemistry, qualitative analysis and the classical methods of quantitative analysis; 2) ability to accomplish the main procedures of classical chemical analysis: qualitative reactions, dissolution, dilution, filtration, heating, weighting, titration, evaluation of the results of the analysis.

Prerequisites for entering the course

General and inorganic chemistry, mathematics and physics are required.

Course aim

The aim of this course is to provide the knowledge about the quantitative and qualitative chemical analysis methods (identification reactions of ions, volumetric and gravimetric analysis), fundamentals of the methods, advantages and disadvantages of the methods, evaluation of the results of analysis.

Content (topics)

 1. Analytical chemistry, qualitative and quantitative analysis methods, separation methods.
 2. Methods of expression of solution concentration.
 3. Analysis procedure:sample collection, preparation for analysis, measurement of analytical signal, evaluation of results.
 4. Measurement uncertainty: the absolute and relative error. Systematic error, random error, error sources and their evaluation.
 5. Sensitivity of the reactions. Reagents used in analytical chemistry. Systemic and non-systemic chemical analysis.
 6. Acids and bases in aqueous solutions: pH, buffer solutions.
 7. Volumetric analysis: basic concept, types of volumetric analysis, ways of titration, standard solutions.
 8. Acidimetric and alkalimetric titration: titration curves, their formation, pH indicators. Application.
 9. Precipitation titration: general principles, titration curves. Equivalent point determination. Absorption indicators. Argentometry, thiocyanate titration, mercurometry.

 10. Oxidation-reduction reactions: galvanic cell, potentials, application of Nernst equation, influence of various factors to redox potential.

 11. Redox titrations: titration curves, redox indicators. Permanganatometry, iodometry, bromatometry, chromatometry.
 12. Formation of complex compounds. Titration using monodentate ligands. Complexonometry: EDTA, its properties, complex of metal ions with EDTA, titration curves, indicators. Application.
 13. Precipitation reactions: solubility product, solubility.
 14. Influence of various factors to solubility: ionic strength, common ion effect, the formation of complex compounds, the pH.
 15. Crystaline and amorphous precipitates, their formation and properties. Coprecipitation, their types and elimination. Gravimetric analysis: general principles of the method, application.

Practical work (contents):

Practical determination of chemical composition of material. Application of systemic and non-systemic chemical analysis for unknown kations and anions in separation as well as the mixture of them in aquatic solutions. Arithmetic calculations of solution concentration, equilibrium constant, solubility, solubility product, pH. Performance of quantitative analysis using volumetric and gravimetric methods, standardization of solutions and calculation of the results.
