During the PTA training, the subject "Chemical-Pharmaceutical Exercises" teaches methods for testing pharmaceuticals according to the pharmacopoeia. The proven textbook by Edgar Schumann supports you in an easily understandable way. With knowledge of analytical techniques, easily memorized key phrases, and concrete descriptions of the laboratory experiments in the practical course, you will be optimally prepared for the exam. After gaining insight into working in the laboratory and conducting analytical preliminary work, exercises for the detection of inorganic ions follow. The quantitative determinations of inorganic substances introduce methods for gravimetric and volumetric analysis. The fundamentals for chemical and physical detection of organic substances and their quantitative determination are the focus of the next part.
