During the semester student have to make seven laboratory experiments (including identification of some products by chemical or instrumental methods of analysis- X-ray structure analysis on powder and monocrystal sample).

The experiments are chosen to supplement and enhance the lecture content of the associated Inorganic chemistry 2 course.
After completion of this course, the successful student will be able to:
1. Apply laboratory skills to synthesize and separate complex compounds associated with Inorganic chemistry 2 course using published reactions, protocols, standard laboratory equipment,
2. Demonstrate safe laboratory skills (including proper handling of materials and chemical waste) for particular laboratory experiments.
3. Analyse and interpret data of the carried out experimental protocol
4. Characterize prepared complex compounds using modern instrumentation.
5. Identify a given inorganic compound based on a series of chemical reactions.
6. Demonstrate knowledge of the element classification to predict important properties of chemical compounds, including stability, solubility, redox properties and reactivity.
