Objective: 

To convey knowledge on fundamentals of analytical chemistry
To strengthen the knowledge on selected aspects of fundamental chemistry, in particular on chemical bonds, structure of chemical compounds, their stability, morphology etc.
To give the skill in calculations of chemical equilibria
To give knowledge of basic analytical reactions and techniques in classical analysis, qualitative and quantitative
To transfer basic information on contemporary instrumental methods in analytical chemistry (spectroscopic, electrochemical, chromatographic, extraction, etc.)

Assessment: 

lecture: written exam, it is possible to correct the note orally.
laboratory: students are expected to perform all the exercises planned. After every part (classical qualitative analysis, classical quantitative analysis, instrumental methods) there is opportunity to complete the tasks or to repeat them to obtain better note.
seminar: permanent evaluation, the final note can be corrected during the final test.

Prerequisites:

Lecture: Role of chemical analysis in studying biological processes. Criterions of choice of chemical reactions for analytical aims (kinetic and thermodynamic). Collection and preparation of samples for analysis, especially the biological materials and drugs. Chemical equilibria in homogeneous systems: acid-base, reductor-oxidizer, metal-ligand, and in heterogeneous systems: solution-precipitate. The factors influencing chemical equilibrium and their analytical consequences. Reactions in non-aqueous solutions. The main analytical techniques including identification, masking, division, and classical methods of quantitative determinations of elements based on the above equilibria (volumetric and gravimetric methods). Examples of advanced determinations of natural samples. Methods: spectrophotometric, electrochemical, chromatographic, extraction - the physical foundations of these methods and their application in examples. Evaluation of the credibility of analytic methods, estimation of errors.

Seminar: Basic definitions. Calculations of concentration. Interionic interactions, Debay-Hückel law. Reactions in one-phase systems. Weak and strong electrolytes. Ostwald equations. Acid-base reactions, calculation of pH of acids and bases (also polyprotic and polyhydroxylic), buffers. Hydrolysis. Amphiprotic electrolytes. Redox equilibria. Nernst potential. Equilibrium of complex formation, stability constans, formation constants. Precipitation, solubility, ionic product. Reactions in multi-phase systems. Titration curves. Indicators. Fundamentals of calculations in instrumental methods of analysis. Application of computer in analysis and data processing.

Laboratory: Selected identification reactions and general rules of identification of cations and anions. Special methods of classical analysis: drop analysis, microcrystalline analysis. Analysis of simple salts, oxides and/or elements. The methods of quantitative transfer of solid sample to solution. Quantitative determinations: alkalimetric, redox, complexometric, gravimetric, precipitation. Physical methods of chemical analysis: atomic emission spectrometry, spectrophotometry UV-Vis, turbidimetry, chromatography (column solid-carrier and thin-layer), coulometry, potentiometry, electrogravimetry, pH-metry. The exercises are performed in 5-hour blocks each preceded by a very short (few minutes) test on the knowledge of the content of instruction for it.
