Aims

The aim of the course is to familiarize students with the course of chemical reactions. The aim of the first part of the practical course in analytical chemistry I, focused on qualitative reactions, is to teach students the characteristic reactions of inorganic ions with a selected set of group and selective reagents, which can be evaluated visually or using simple instrumentation. The aim of the second part of the practical course in analytical chemistry I is to introduce students to the issues of quantitative analytical chemistry, to master and adopt basic analytical methods in the field of gravimetry, volumetry, potentiometry and voltammetry.

Completing the course will increase the students' competences as follows:

1. They will have a detailed overview of analytically and technologically significant reactions of common ions.

2. They will deepen their knowledge of the reactivity and some physical properties of groups of common elements and ions.

3. They will be able to apply the selection of analytically significant reagents and indicators in a creative way. 4

4. They will be introduced to the technique of microscopic reactions and reactions in small volumes.

5. They will master precise work in the analytical laboratory, preparation of standard solutions and samples.

6. They will master all calculations used in gravimetry, volumetry and electrochemical methods.
