First part of laboratory exercises is oriented to qualitative analysis of cations and anions using wet chemistry procedures. Quantitative determination of analyte based upon various titration procedures follows. In the last part of exercises students become acquainted with basic instrumental methods of chemical analysis.


Knowledge of analytical chemistry on the level of a completed basic university course.

Syllabus of lectures:
Syllabus of tutorials:

1. Qualitative analysis of inorganic cations and anions using wet chemistry: identification of two cations in mixture, identification of two anions in mixture.
