Introduction to Chemistry 1300-WWZCH
At the exercises (3x45 minutes) there are carried out following topics:
1. Periodic Table of Elements and properties of elements. The law of periodicity: volatility atomic radius, ionization energy, electron affinity, electronegativity on the periodic table of elements.
2. Nomenclature of the chemical compounds, calculating the degree of oxidation of the elements in the compounds, reactions which lead to formation of acids, bases and salts.
3. Explain the concept: concentration percentages, molar concentration and percentages concentration conversion – exercises. Titration analysis.
4. Stoichiometry reaction – excercises. Explain the concept: pH and pOH of solutions, the pH scale, pH from the concentration of the solution.
5. Dissociation of the different compound, the degree of dissociation - α, the dissociation constant – K, the power of acids and bases based on the dissociation constant (K)
6. Hydrolysis of different types of salts (acid salts and basic salts), pH of hydrolysing salt - exercises, buffer solutions and the principle of their operation.
7. The definition of unsaturated, saturated and supersaturated solutions. The definition of the solubility equilibrium and molar solubility - exercises. Factors influencing the solubility of sediments.
8. The complexes - the central atom, ligand, chelate ligand, the coordination number, complex ion. Nomenclature of the complex ions and compounds. Amphoterism - elements forming oxides and hydroxides of amphoteric - position in the Periodic Table. The reactions of metals, oxides and hydroxides of amphoteric with strong acids and strong bases.
9. Electrolysis - reactions occurring at the anode and the cathode during the electrolysis of salt, acids and bases. Reactions of acid and metal with 1) a negative standard potential 2) a positive standard potential.
10. Oxidation and reduction reactions (redox). The rules for calculating the formal oxidation state of the elements in relationships. Definitions: the process of oxidation and reduction, oxidizer and reducer, examples reducers and oxidants, redox reaction.

Assessment criteria
The final, single choice test takes place on the last meeting. A student passes the exam after reaching 60% of the points. A student has the right to join the retake test. A student's absence at the first date of the test should be justified, in the case of the lack of justification a student is entitled only to the correction date. A student has the right to two unjustified absences during the semester.
Practical placement
none
