Learning Objectives

 

The course has the main aim to provide students of the general chemistry bases taking into account the theoretical and applicative aspects. The main goal is to supply students of the right knowledge to can understand and analyze the matter, its properties as well as its transformations under the chemical point of view, mainly considering the biotechnological field. In particular, the student will be able to use the chemical language, to understand and to use correctly the molecular formula and to foresee the chemicophysical characteristics of a compound as its reactivity on the base of its structure and elemental composition.

Learning Achievements (Dublin Descriptors)

The course, directed to first class students, has the aim to provide the general chemistry bases together with the main inorganic information. It intends to supply the instruments to analyze and to stiochiometrically quantify a chemical process, developing the atomic-molecular vision of the matter.

The student must demonstrate to possess the mastery of base knowledge with respect to:

- Writing and reading the chemical formula of an inorganic compound

- The prevision of the acid-base and red-ox behavior of main compounds

- The Stoichioemetry calculus of the chemical reactions

- Solutions and concentration uses and measures as well as methods for the preparation of a solution.

- Physical properties of a solution

- pH calculus of acid-base and buffer solutions.

The student must demonstrate the understanding of the concepts and theories provided for the course. He must be able to state concepts supplying adequate examples.

The student must demonstrate to possess the capacities to utilize the theoretic knowledges for suggesting solutions to problems and questions asked by the teacher.

Teaching Material

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

Didactics, Attendance, Course Books and Assessment

Didactics

The course consists in lecturers and stoichiometry together with practical experiences to favor the comprehension.

Students can attend the lectures asking explanations to the teacher  

Course books

Fusi, Bacchi, Giorgi, Marchetti, Messori, Paoli, Punzo, Sortino, Tolazzi. Chimica generale e inorganica. Idelson Gnocchi editore

Assessment

The verification of the knowledge provides a written and oral examination

The aim of the written examination is to verify the student competences with respect to the balance of a chemical reaction as well as to the stoichiometric calculus of treated subjects

The aim of the oral examination is to verify the student preparation with respect to the writing of a chemical formula, to the prevision of the chemicophysical properties of the main compounds (oxides, hydrides, acids, bases, salts) as well as of concepts, explained during the course. The student must be able to furnish appropriate examples concerning the argument to demonstrate the full comprehension of it.
