Course abstract

In this course students learn basic laws of chemistry, physical and chemical properties of metals, structure of matter, colligative properties of solutions; chemical kinetics and chemical balance. The part of electrochemical processes covers the potential theory of electrodes, galvanic elements, electrolysis and its application, electrochemical corrosion, and protection against it. Light, heavy metal construction.

Learning outcomes and their assessment

Knowledge and critical understanding of the chemical properties of metals in light and heavy constructions; processes in galvanic cells, electrolysers, and electrochemical corrosion and protection. (4 tests and 4 colloquiums).
Skills to analyze, compare and evaluate the resistance and reactivity of metals and their alloys under different conditions, to explain the influence of various factors on the rate of chemical reactions; to evaluate the possibilities of various galvanic elements and to find creative solutions for corrosion prevention in given conditions – 3 laboratory works.
Competence to objectively evaluate new information, to independently acquire and analyze information, as well as to use it in solving chemistry-related issues and practical work problems - 3 protocols of laboratory work, 8 tasks of independent work.

Requirements for awarding credit points

Type of examination - exam in 1st semester. If 3 laboratory works were worked out and pass during the semester, 8 independent works were pas, 4 tests were successfully written and 4 colloquiums, whose average grade was 5 points and higher, then the student has the opportunity to receive accumulative exam evaluation. If students are not satisfied with their assessment, there is a possibility to take a written examination. The examination is compulsory if the average mark is lower than 5 points.

Description of the organization and tasks of students’ independent work

Preparation for tests, performing tasks of independent work, processing of laboratory work reports, processing of results obtained in laboratory work.

Criteria for Evaluating Learning Outcomes

The overall assessment of the study course consists of evaluations of the written tests and laboratory works, as well as the completion of independent work. Final grade of the study course will be calculated using a marking scheme: • tests 30%; • colloquium 40% • laboratory reports 20%. • independent work 10%; Student must earn a positive mark (at least 4) for every course activity to pass the course.
