Course abstract

In the study course “Inorganic chemistry” students are acquainted with the basic theoretical issues of general chemistry. This course of study gives the review of biologically most important chemical elements, emphasizes their biological importance and their use in the veterinary medicine

Learning outcomes and their assessment

Students are able to show deep knowledge of important issues of the general chemistry as well as the chemical elements important for biological systems.
In the study course students master skills of carrying out the chemical experiments, as well as the quantitative determination of some chemical compounds with classical and instrumental methods of analyses. Obtained theoretical and practical skills allow to acquire organic chemistry, biochemistry and pharmacology.
Students are able independently formulate and critically analyze problems connected with the influence of biogene elements on human and animal organisms

Requirements for awarding credit points

At the times indicated by the lecturer, the student writes 3 tests and 3 theory tests, performs 5 laboratory works and submits protocols.

Description of the organization and tasks of students’ independent work

The student independently gets acquainted with the possibilities of instrumental methods of analyses, their advantages and disadvantages

Criteria for Evaluating Learning Outcomes

The student can take the exam if all laboratory works have been completed at the scheduled times, protocols have been accepted, 3 tests and 3 theory tests have been successfully written. If average mark in the tests is not less than 6 (almost good), the exam may not be taken
