ECTS:

10

Study level:

basic academic studies, integrated basic and graduate academic studies

Study programs:

Environmental Chemistry: 2. year, winter semester, compulsory course

Chemical Education: 2. year, winter semester, compulsory course

Teacher:

Aleksandar Đ. Lolić, Ph.D.
associate professor, Faculty of Chemistry, Studentski trg 12-16, Beograd

Assistant:

Đurđa D. Krstić
assistant with PhD, Faculty of Chemistry, Studentski trg 12-16, Beograd

Hours of instruction:

Weekly: two hours of lectures + one hour of exercises + six hours of labwork (2+1+6)

Goals:

Helping students acquire basic knowledge of quantitative chemical analysis (gravimetry and volumetry); introducing students to the procedures of taking representative samples; selecting and applying the most appropriate methods; assessing approaches in the course of solving problems during the analysis of complex i.e. real samples; developing skills, accuracy and precision necessary for working in a laboratory.

Outcome:

The student is qualified to choose the appropriate method for quantitative analysis of the sample and to perform the determination with the required accuracy and precision.

Teaching methods:

Lectures, laboratory work (group and individual) and theory exercises.

Extracurricular activities:

The student goes over the results obtained during group activities and records the results in his workbook, does calculation problems and other kinds of problems and elaborates the principles of the analysis.

Colloquia:

20 points

Remarks:

Students take the tests, on the lab session terms, after each area -  five of them; the students qualify for a test only after they have finished group exercises (except for gravimetry), which has to be verified by the teaching assistant; the progress test consists of a problems  and  theoretical quastions. The  test carries a total of 4 points.

Written exam:

20 points

Oral exam:

30 points
