Prerequisites:

For a comprehensive understanding of the topics of the course, a strong basis of General and Inorganic Chemistry is needed. Therefore, students are warmly encouraged to take that exam before starting the course.
The exam can be taken after passing the Analytical Chemistry exam.

Objectives

At the end of the course, the student shall reach the following objectives:
- Comprehension of chemical equilibria mechanism and management of multiple equilibria in water solution.
- Knowledge of chemical behavior of main cations and anions.
- Ability to set up a separation and identification protocol of a simple mix of inorganic compounds.
- Knowledge of the pharmaceutical, pharmacological and toxicological role of most important cations and anions.
- Learning of principal lab operations through practical lab experiences.
- Knowledge of the most important safety rules in the lab practice.

Extended Syllabus

Introduction to the qualitative inorganic analysis
Properties and characteristics of elements and inorganic compounds.
General aspects of the laboratory procedures
Main semi-micro analysis techniques: evaporation and boiling, calcination, melting, filtration, centrifugation, and washing of precipitates.

Methods of Provision

Conventional

Teaching Methods

The course is organized into 32 hours of taught class and 24 hours of lab practice. The theoretical aspects of the analysis of pharmaceutically relevant inorganic compounds will be discussed during the lectures.
The lab practice, single-seat, is organized so that the student can deal with lab practice and carry out the analysis explained in the taught-class.

Evaluation methods

Verification of learning:

The final exam consists of an oral examination lasting 30-40 minutes, aimed to verify the comprehension of general concepts of the analysis in water solution, also through the resolution of exercises. Gaps in the basic knowledge of General Chemistry concepts will not be tolerated. The exam will be completed by verifying the knowledge of the pharmaceutical and toxicological role of inorganic compounds and instrumental analysis techniques. The result of the lab tests will contribute to the final evaluation.
