Course abstract

The aim of the study course is to master the basic laws of chemistry, which creates an understanding of the importance of chemistry in mechanical engineering and metalworking. Students acquire the physical and chemical properties of metals, their compounds and alloys, quantitative composition and colligative properties of the solutions; as well as chemical kinetics. The Electrochemical Division covers the potential theory of electrodes, galvanic elements, electrolysis and its application, electrochemical corrosion, and protection against it.

Learning outcomes and their assessment

1. Knowledge and critical understanding of the chemical properties, applications of light and heavy metals and their compounds, processes of galvanic elements, electrolysers, and electrochemical corrosion and protection against it - 4 tests.
2. Skills - ability to analyze, compare and evaluate the resistance and reactivity of metals and their alloys under different chemical 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 - 4 laboratory works.

3. 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 work problems - 4 laboratory work protocols, 8 tasks of independent work.

Requirements for awarding credit points

Written exam in 2nd semester. In order to pass the exam, during the semester, student should have worked out and pass 4 laboratory works, 8 independent works, successfully written 4 tests. The examination task consists of a section on the theoretical material acquired during the course and a practical task related to the chemical properties of metals, practical application in galvanic elements and anti-corrosion coatings.

Description of the organization and tasks of students’ independent work

8 independent work for successfully preparing for tests. Writing the protocols for laboratory works, evaluating of experimental results obtained in laboratory works.

Criteria for Evaluating Learning Outcomes

The assessment of the study course depends on the assessment of the examination task and the results of the 4 tests.
Students who have at least “6” in test grades are not required to write a theoretical part of the examination and their grade for this part is made up an arithmetic mean of grades in tests during the semester.
The examination grade is calculated as the arithmetic mean of grades obtained in two examination assignments.
