CHIMICA GENERALE ED INORGANICA E LABORATORIO

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).

  The aim is give a basic knowledge on electrochemistry and inorganic systems and some practical skills in order to solve simple problems.
