Tematika

Within the frame of the theoretical and practical trainings of this subject students will study the analytical approach of chemistry. This approach is crucial for the study of almost all pharmaceutical sciences like pharmaceutical chemistry, pharmaceutical technology etc. Students have to learn and examine the theory and practice of analytical reactions, methods, rules and calculations. Students will learn how to identify an unknown inorganic sample in both simple and complex manner of the analysis. At the end of the semester they should be able to know how to analyze an unknown sample for the most important cations and anions. Students should prove to demonstrate that they know how to use the theoretical knowledge in the pharmaceutical practice while finding out what their unknown sample is.

A félév elfogadásának feltételei

The maximum number of absences is three. Above this number the acceptance of the semester is to be refused!

Félévközi ellenőrzések

Only those students are allowed to have an exam at the end of the semester, who completed both the theoretical and practical courses successful.

Two compulsory midterm tests (on the topics of the lectures and the practices) will be written during the semester on the 6-7th and the 11-12th weeks. One of the test results should be above 60%, and the average of the tests should be above 50%. One retake test is allowed on the 14th week of the semester.

Exam topics/questions: The semester is closed with a written final test. The minimum acceptable result is 60%. The final grade is calculated on the results of the final test, two written mid-term tests and the overall result of the practical work throughout the semester.

Távolmaradás pótlásának lehetőségei
