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 topic ends with a practical grade. A student with a failed grade is not allowed to enter the exam! The students are supposed to have at least passmark for both midterm tests and a 70% practical result for a license for entering the exam!

Félévközi ellenőrzések

The topic ends with a practical grade. A student with a failed grade is not allowed to enter the exam! The students are supposed to have at least passmark for both midterm tests and a 70% practical result for a license for entering the exam!

The knowledge and practical ability of the students will be measured by "ion searching "tests. That means, that they will be given certain amount (number) of unknown analytical samples to be identified by the usual chemical reactions, possible analytical methods! Every student will have his or her own sample set for individual practical work. The result of this work must be above 70%! If necessary, the instructor measures the students' theoretical knowledge by a mid-term laboratory tests.

Távolmaradás pótlásának lehetőségei

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