Periodic system of the elements and periodicity of some of their properties depending on their position in the periodic system. Chemical bond types and chemical properties caused by them. Law of mass action and chemical equilibria: acid-base equilibria, amphoteric hydroxides, complex equilibria, solubility equilibria.
Redox reactions and introduction to the electrochemical series.
Stoichiometric calculations.
Identification of selected cations and anions in aqueous solution.
Laboratory safety.

Previous knowledge expected

None
The attendance in the lecture course ”Introduction to General and Analytical Chemistry“ (771100) is highly recommended. The practical course starts after the theoretical basics have been discussed in 771100.

Objective (expected results of study and acquired competences)

After successfully passing this course the students gained practical knowledge of fundamental principles of general and analytical chemistry.
They are familiar with the most important codes of behaviour, safety precautions and safety installations, they know how to handle chemicals safely and they are able to use a safety Teclu burner and glassware. Moreover, they know how to dispose of chemicals professionally and they also practised it.
The students know, beside others, especially the alkali metals, alkaline earth metals and the halogens of the periodic table and know some trends of their properties depending on their position in the periodic system, this means that they know how chemical properties change within a group of the periodic table. They are able to classify a chemical substance according to the chemical bond type.
The students are able to describe basic inorganic reactions in aqueous solution including simple qualitative analysis of selected cations and anions and they know what is important and on what they have to pay attention during analysis.
They are able to differentiate between the terms mole (amount of substance) and molar concentration and they are able to use them correctly.
The students are able to formulate laws of mass action and chemical equilibria: acid-base equilibria, complex-equilibria, solubility-equilibria, redox-equilibria and coupled equilibria and to perform simple calculations based on them. That means, they know how to use the law of mass action, they know and understand the differences between strong and weak acids (bases) and acid-base equilibria; they know buffer (- solutions) and how they work; they are able to calculate pH values; they know how salts react when they dissolve in water and why they react in this way. They know which cations build poorly soluble hydroxides; they know amphoteric hydroxides and how those behave. The students know how to simply determine the stability of iron(III) complexes; they know redox reactions and how to use the electrochemical series.
