GENERAL CHEMISTRY AND LABORATORY - MOD.1

The course is the basic training activity for the chemistry area in the Degree in Chemistry and Sustainable Technologies, and allows the student to acquire the first knowledge of the main concepts in chemistry, leading the way to the following courses where most part of the topics will be faced again and strenghtened.

The approach to the most relevant physico-chemical phenomena starts from a storical and/or descriptive point to obtain or present the mathematical expression of the Laws of Chemistry. Complementary is the teaching of stoichiometry (which is present only in this course) as the pratical and numerical calculation of the variabiles in real chemical systems or as the result of different analytical techniques.

Specific learning targets are: a) basic knowledge on matter structure (atoms, molecules etc); b) highlight relationships among macroscopic physical and chemical properties and atomic and molecular characteristics; c) a knowledge of chemical equilibria in general and in acqueous solutions (acids, bases, solubility); d) introducing the energetics of chemical transformations (chemical thermodinamics) and its predictive abilities; e) giving basic concepts in electrochemistry and their practical applications (cells, corrosion etc); f) exploit the ability to make exact and appoximate calculation applying the Laws of Chemistry and Stoichiometry in practical situations (numerical exercises and lab work).

1. Knowledge and comprehension
a) The students are expected to master the properties and chemical behaviour
of atoms and molecules on the atomic scale and how these behaviour
determines the macroscopic properties and reactivity of elements and
compounds.
b) They will have to master the quantitative laws that rule physical and
chemical equilibria, and energy exchange in electrochemical systems.

2. Ability to apply knowledge and comprehension
a) students must become able to calculate concentrations/pressure etc for species involved in equilibria and redox reactions.
b) Students are expected to be able to put in relation bulk properties of substances to atomic and molecular properties, depending on the type of bonds present in the molecules.

3. Ability in management
a) At the end of the course they should be able anyway to solve, by logical
and rigorous scientific reasoning, problems in stoichiometry using their
chemical and mathematical knowledge.
b) They are expected to be able to interpretate experimental facts in the light of chemical theories (atomic structure, bond, equilibria etc).

4) Ability of communicate
a) They are expected to be able to communicate and explain, in the correct
chemical terms, all the contents of the course.
b) They should be able to report simply but rigorously on their lab
experiences, in written form.

5) Ability to learn
a) Students are expected, on the bases of the acquired knowledge, to be able to follow and comprehend the lectures of the following, more specialized course,
b) Students are expected to be able to take notes and select informations according to their priority and value.

- Laboratory issues

A preliminary written examination on stoichiometry exercises (five
excercises, 2.5 hours), then (if succesfully fulfilled) an oral
examination on the more theoretical part of the course.
The lab reports will have a weight (positive or negative) on the global
final evaluation.

Classroom lectures with PowerPoint presentation of the material.
Classroom lectures with blackboard to develop demostrations and/or numerical examples and exercises.
The PowerPoint files utilized are available to the students via Moodle interface.
