Learning objectives
Two didactic units composes the course: lectures (Inorganic Analysis of Substances having Pharmaceutical Interest) and individual laboratory training (Qualitative Analysis Laboratory).
The main topics of the lectures are the in-depth analysis of the preparatory courses knowledge (General and Inorganic Chemistry, and Stoichiometry and Analytical Chemistry) applied on the qualitative analysis and the learning of laboratory safety rules, basic techniques of the practical experimental chemistry and the analytical procedures to apply during the laboratory experiences, focused on the identification of the inorganic compounds of medicinal and toxicological relevance.
Concerning the experimental practices, the students will improve the technical ability to identify the inorganic substances prescribed by Italian and European Pharmacopoeias.
Expected learning outcomes
By the lectures, the students will improve their knowledge concerning the theoretical and practical aspects related to the qualitative analysis, which they will apply during the individual experimental practices.
By the laboratory experiences (mandatory), the students will acquire expertize to perform the qualitative analysis of inorganic compounds, to complete their knowledge (by means also of other courses: Principles of Quantitative Pharmaceutical Analysis and Laboratory for Quantitative Analysis, and Assays and Methods of Analysis of the Pharmacopoeias and Laboratory of Drug Identification), needed to take the qualifying examination of Pharmacist.

First semester
Course syllabus
Program of the lectures:
- Introduction to the inorganic qualitative analysis.
- Safety guidelines in chemistry laboratory and hazard prevention.
- Basic laboratory procedures.
- Theoretical aspects of the dissolution and precipitation processes.
- Salt hydrolysis: acid/base properties of anions, cations and salts.
- Analysis of anions.
- Analysis of cations (analysis by precipitation of six analytical groups).
- Identification methods for unknown inorganic compounds listed in the European Pharmacopoeia (water-soluble and water-insoluble substances).
- Limit tests: principles reported in F.U.
- Introduction to the pharmaceutical, toxicological and biochemical properties of the inorganic compounds analyzed during the laboratory work.

Program of the practical laboratory experiences:
- Introduction to basic techniques in laboratory practice.
- Anion recognition assays.
- Cation recognition assays (periodic analysis by precipitation of six analytical groups).
- Identification of unknown inorganic substances listed in the European Pharmacopoeia (water-soluble and water-insoluble substances).
Prerequisites for admission
The course takes place in the first semester of the second year. The students are expected to have a basic Inorganic Chemistry knowledge.
Teaching methods
The course includes both lectures (Inorganic Analysis of Substances having Pharmaceutical Interest unit) and practical laboratory experiences (Qualitative Analysis Laboratory unit).
The unit of Inorganic Analysis of Substances Having Pharmaceutical Interest (5 CFU) consists in lectures preparing the students to experimental laboratory training, which take place at the same time.
The unit of Qualitative Analysis Laboratory (2 CFU) consists in eight individual obligatory laboratory sessions.

Assessment methods and Criteria
The final exam consists of a written test of 13 questions that must be completed in 90 minutes. Each question can be evaluated with a maximum of 2/30 for a total amount of 26/30. The remaining 4/30 derive from the evaluation of the laboratory activity (Qualitative Analysis Laboratory unit).

Course syllabus
The course (II term) is focused on the qualitative analysis of the elements constituting the inorganic substances included in the Italian Official Pharmacopoeia, allowing their identification. It is composed by two didactic units:
- Inorganic Analysis of Substances having Pharmaceutical Interest (20 lectures, 5 CFU, recommended attendance)
- Qualitative Analysis Laboratory (8 experimental practices, 2 CFU, mandatory attendance)
Inorganic Analysis of Substances having Pharmaceutical Interest didactic unit program:
- Introduction to the inorganic qualitative analysis.
- Safety guidelines in chemistry laboratory and hazard prevention.
- Basic laboratory procedures.
- Theoretical aspects of the dissolution and precipitation processes.
- Salt hydrolysis: acid/base properties of anions, cations and salts.
- Analysis of anions.
- Analysis of cations.
- Identification methods for unknown inorganic compounds listed in the Italian Pharmacopoeia (F.U.I.) (water-soluble and water-insoluble substances).
- Limit tests: principles reported in F.U.I.
- Color theory: electronic properties-color relationships of ions and molecules.
- Introduction to the pharmaceutical, toxicological and biochemical properties of the inorganic compounds analyzed during the laboratory work.

Qualitative Analysis Laboratory didactic unit program:
- Basic laboratory procedures.
- Salt hydrolysis: acid/base properties of anions, cations and salts.
- Analysis of anions.
- Analysis of cations.
- Identification methods for inorganic compounds listed in the Italian Pharmacopoeia (water-soluble and water-insoluble substances).
Prerequisites for admission
Knowledges concerning General and Inorganic Chemistry, Stoichiometry and Analytical Chemistry (preparatory courses) are required.
Teaching methods
The lectures are offered by PowerPoint presentations concerning the general topics (including some ongoing exercises) and the introduction to the laboratory experiences, to carry out during the individual experimental practices.
