Learning Objectives
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.
Course Structure
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
Detailed Course Content
Theoretical lessons (3 CFU)
Electrochemistry
· Basic on the electrochemical cells. Conductors of I and II species. Voltaic cells. Galvanic semielements. Hydrogen electrodes and standard electrode. Electrochemcal series. Free energy and electrical work. Nerst law. Electrochemical cells. Electrochemistry products and Faraday laws.
Chemical bond and structure of solids
• Classification of solids. Ionic and covalent solids.Ionic bond: lattice energy and Madelung constant. Structure of solids: amorphous and crystalline solids. Structures and properties of metals.
Salt solubility in water
· Solubility. Energy of the solubility process. Low solubility salt. Solubility equilibrium and solubility product.
Chemistry of s-p elements
• Introduction to the elements and periodic properties. Main groups: Hydrogen and groups 1°-2° and 13°-18°. General characteristics of the elements of the main groups. Natural abudance. Reactivity of the elements. Preparation methods. Compounds with hydrogen, oxygen and alogens. Salts and other compounds
