Learning objectives
The student gains the principles and the analytical procedures for the characterization of chemical compounds, possesses basic knowledge of quantitative chemical analysis, with reference to the analytical aspects of chemical equilibria, and to the methods of volumetric analysis. The student is also able to perform stoichiometric calculations and practical operations in relation to the preparation of solutions with known concentration and is able to choose and use the best method of separation, purification and analysis of chemical mixtures
Prerequisites
No
Course unit content
The course is focused on the systematic treatment of homogeneous and heterogeneous equilibria treated in an analytical key and applied to quantitative volumetric analyzes, proposed in the relative laboratory experiences

Teaching methods
Frontal classes dealing with demonstrations concerning the systematic treatment of chemical equilibria, including the guided solution of problems relevant to the aforementioned equilibria. Description of the purposes, methods and procedures for the execution of the proposed laboratory practical demonstrations.
Assessment methods and criteria
The student compiles a laboratory report, in electronic format, showing the results and conclusions of the laboratory experience. After passing the written test, which requires the solution of problems and questions dealing with the chemical equilibria treated in the course, the student is admitted to the oral examination, during which the written test is discussed, the report and the overall knowledge of the arguments are verified.
