Practical Chemistry for Electrical Engineers
FEKT-BPC-PCEAcad. year: 2020/2021
Atoms, molecules, orbitals, hybridization. Reaction, oxidation, reduction. Materials for electrotechnique. Liquids, gases, solutions and their physical properties. Chemical equilibration and reaction rates. The introduction to laboratory technique. Corrosion, surface treatment of materials. The introduction to photochemistry and electrochemistry. Electrochemical methods, electrochemical impedance spectroscopy.
Learning outcomes of the course unit
The student will gain theoretic and applied knowledge in fundamentals of chemistry and electrochemistry. Based on this, the student will be able to precisely and safety perform any common laboratory practices, which are necessary for operation in chemical and electrochemical laboratories.
The subject is conceived as introduction to chemistry for students of electrical engineering, thus it does not requires any prerequisites except the knowledge of chemistry from secondary school and mandatory subjects of Electrotechnique I and II.

Planned learning activities and teaching methods
The methods of teaching are dependent on teaching process and are described in article 7 of Study and examination order of BUT.
Assesment methods and criteria linked to learning outcomes
The student will gain 20 points after performing all laboratory exercises and correct elaboration of all protocols. The final examination from laboratory knowledge will be scored by another 20 points. The minimal extent for elaboration of each laboratory exercise will be set by yearly actualized order of subject garant. Final oral examination will be scored by maximum of 60 points. The final exam will take place in person and remotely.
