Tematika

One of the main tasks of this subject is to encourage participants to think analytically.

This type of conscious way of thinking is essential for the later acquisition of pharmaceutical analysis, pharmaceutical technology and pharmaceutical chemistry.

In order to achieve the tasks and goals, our students learn the theoretical application and regulation of various chemical reactions within the framework of qualitative chemical analysis. They receive theoretical training for all this in lectures, where they also learn about the safe handling of hazardous substances and the protection of water resources.

They carry out their practical work with the theoretical knowledge, during which they apply modern material and energy-saving analytical procedures. Through the combined knowledge acquired in lectures and practical sessions, they become capable of qualitatively analyzing any studied inorganic sample as an unknown, keeping in mind the reduction of environmental burden. With the help of their acquired knowledge in the field of cations and anions, they learn the rules of analytical thinking and the principles of ethical scientific practice. They report on their knowledge in a written colloquium at the end of the semester.

A félév elfogadásának feltételei

The topic ends with a practical grade. A student with a failed grade is not allowed to enter the exam! Students write a short test in each class based on the class material that day, the average of which must reach 60%. The students have to identify at least 70% of the unknown ions.

Félévközi ellenőrzések

The topic ends with a practical grade. A student with a failed grade is not allowed to enter the exam! Students write a short test in each class based on the class material that day!

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%!
