Assessment: 

lecture: written exam, it is possible to correct the note orally.
laboratory: students are expected to perform all the exercises planned

Prerequisites: 

The course „Fundamentals of chemistry” (1st semester) credited

Contents: 

Lecture: 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. Selected instrumental methods in analytical chemistry - physical foundations, construction of typical devices, examples of determinations of natural samples. Evaluation of the credibility of analytic methods, estimation of errors.

Laboratory: Six laboratory sessions, 5h each. Five tasks are performed individually or in pairs, according to schedule. Each exercise will be preceded by short test on the content of instruction. The sixth session is for completing tasks or correcting notes. The exercises are:

  • Acid+base and pH+metric titrations of H3PO4 in Pepsi, citric acid in citrons etc.

  • Distillation+densitometric determination of ethanol in beer or wine.

  • Paper (tissue) chromatography or thin-layer one: different solvents, markers or natural dyes. Separation of plant extract in column solid-carrier chromatograph.

  • Mineralization (in mineralizator) natural samples: leafs, milk in powder, tea, spices etc. After mineralization students perform classical identification of Fe and Zn. Quantitative determination of these elements using ICP.

  • Turbidimetric determination of sulphates or chlorides in natural water.
