Learning objectives
The course, which includes practical training, allows the student to approach the practice of chemistry for the first time, particularly of analytical chemistry. Its main purpose is the learning of correct, accurate and conscious "modus operandi" in the elementary analytical chemistry procedures. To achieve this goal, the fundamental principles of qualitative chemical analysis are illustrated in the lessons and implemented in subsequent experimental laboratory, with particular regard to inorganic substances of pharmaceutical and toxicological interest. Furthermore, the student has the opportunity to perform many recognition procedures described in the Italian and the European pharmacopoeias.
Expected learning outcomes
At the end of the course, the student will acquire the basics of the analytical methods applied in the analysis of inorganic substances of pharmaceutical interest. The student will be able to choose the analytical method suitable for the solution of a analytical problem and will be also capable to apply the basic techniques for the analysis of an unknown substance. More specifically, the student, starting from a sample of inorganic drugs, will characterize the chemical composition indicating, at the end of the analytic procedure, the brute formula of the analyzed substance. Furthermore, the student will acquire the basic notions of the pharmacological and / or toxicological properties of inorganic substances of pharmaceutical interest.
During the final examination, the students will demonstrate to comprehend the proposed questions and they will be able to process the knowledge acquired during the lectures and the practical training.

First semester
Course syllabus
The course focuses on the following topics: (i) safety rules in a chemical laboratory; prevention of laboratory risks; (ii) general information on operations and laboratory equipment; (iii) introduction to inorganic qualitative chemical analysis; (iv) theoretical aspects of solubilization, extraction and precipitation processes; (v) oxidation-reduction equilibria in relation to pH and precipitation; (vi) formation of complexes and their stability as a function of pH. Dissolution of precipitates by complexation; (vii) analysis od cations by classical systematic analysis with subdivision into the six analytical groups; (viii) analysis of anions; (ix) guide to the identification of water-soluble inorganic substances of the EP; (x) guide to the identification of water-insoluble inorganic substances; (xi) biochemical, chemical-pharmaceutical and toxicological properties of the inorganic substances under analysis; (xii) limit tests.
Prerequisites for admission
To successfully follow the lessons of this course, the student must have basic knowledge of general and inorganic chemistry.
Teaching methods
Frontal lessons and individual practical training.
Teaching Resources
The powerpoint presentations used for the lessons are available to students on UniMi's Ariel platform.
For further information, the following texts are recommended:
- A. Araneo, Chimica analitica qualitativa, Casa Editrice Ambrosiana.
- F.P. Treadwell, Chimica Analitica, Analisi qualitativa, Casa Editrice Vallardi.
- G. Svehla, Vogel'sQualitative Inorganic Analysis, John Wiley & Sons, New York.
- G. Charlot, Analisi Chimica qualitativa, Piccin Editore, Padova.
- Farmacopea Ufficiale della Repubblica Italiana X e XI Ed.
- Farmacopea Europea IV Ed.
Assessment methods and Criteria
The exam consists of two tests: practical and written ones. In the practical test, the student has to recognize 4 single inorganic salts and two inorganic salts in a mixture, totaling a maximum of 6/30 points. The written test is based on specific questions (both theoretical and applicative) in which the student can score the remaining 24/30 points.
The evaluation of the test will take into account the student's ability to know how to apply the main methods of qualitative analysis in order to identify inorganic active ingredients reported in the Pharmacopoeia and the ability to independently manage the related analytical problems.
