Course abstract

In this study course students acquire basic laws of chemistry, structure of matter; colligative properties of solutions; colloidal state of the substances. The Electrochemical processes covers the potential theory of electrodes, galvanic elements, electrolysis and its application, chemical and electrochemical corrosion, and protection against it. The properties and application of structural metals are studied.

Learning outcomes and their assessment

Knowledge and critical understanding of the physical and chemical properties of structural metals, the colligative properties of solutions; processes in galvanic cells, use of electrolysis for metal coatings, as well as electrochemical corrosion and protection against it - tests.
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 possibilities of various galvanic elements and to find creative solutions for corrosion prevention in given conditions - laboratory works.
Competence to objectively evaluate new information, ability to independently acquire and analyze information, as well as to use it in solving chemistry related problems and practical tasks - protocols of laboratory works, tasks of independent work.

Requirements for awarding credit points

Test with a grade in the 1st semester. To pass the test, you must have worked and counted for 7 laboratory works, counted for 8 independent assignments, successfully written for 8 tests. The tag is formed as an average mark from the successfully written check marks.

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 60%;
• laboratory reports 30%.
• independent work 10%;
Student must earn a positive mark (at least 4) for every course activity to pass the course.
