Tematika

Topic
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

Maximum of 15 % absence allowed

Félévközi ellenőrzések

The topic ends with a practical evaluation. A student with a failed practical grade is not allowed to enter the exam! The students are supposed to have 70% practical result for a license for entering the exam!
Two compulsory midterm tests (on the topics of the lectures and the practices) will be written during the semester on the 5-6th 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 re-take test is allowed at the 14th weak of the semester

Exam topics/questions
The semester is closed with a written test. In the case the result will not reach the 60% level, the student fails, she or he has to repeat the exam. In all other cases (above 60%), the student will receive a grade from qualitative inorganic analysis, based on the results of the two written tests and the overall result of the practical work throughout the semester (maximum score: 5 points).

Távolmaradás pótlásának lehetőségei

All missed practicals are to be recovered on the next meeting (next week).
