Learning objectives

Basic Knowledge:
The student will be prepared to a correct and deep understanding of the fundamental mechanisms which govern the chemical transformation of matter in the main fields of interest for the Environmental and Land Management Engineering. In particular the attention will be focused on thermodinamic, chemical equilibria between phase and electrochemistry.

the student will be encouraged: A) to illustrate the chemical theory with a rational approach; B) to demonstrate that the interconnections between the various aspects of the theory are well known; C) to achieve a Language scientifically-oriented.


The student must have the basic knowlege of mathematic and physic necessary for the first year courses.

For the theory: “Lezioni di Chimica per Ingegneria”, Author, F. Ugozzoli, Libreria Medico Scientifica, Parma (
For the exercises: “Come risolvere i problemi di chimica”, Author: F. Ugozzoli, CEA – Casa Editrice Ambrosiana.

Teaching methods

The lectures will be presented on the blackboard but can be integrated, when necessary, with the use of multimedia. The students will be encouraged to ask for question during the lectures.
Beyond the lectures, the teacher will be always ready to help the students with discussions and supplementary exercises.

Assessment methods and criteria

The examination consists of a written test in which the student should solve some numerical problems and to illustrate some theorethical concepts. A good result of the test is a prerequisite to be admitted to the oral test.
