Learning Objectives

• Module I
  

  The course is aimed to learn the basic concepts of general chemistry and stoichiometry.

• Module II
  

  To give a basic knowledge of Inorganic Chemistry with particular attention on the elements of the s an p groups and to integrate the basic concepts of foudamental chemistry with specific arguments (structure of solids, solubility equilibrium and electrochemistry).

  This module which is organized through lectures(3 CFU), exercises and lab practice (3CFU) gives the needed information to understand the chemical behaviour of some simple inorganic systems
