Objectives
This is a course designed to give the basic chemistry background indispensable not only for the successive more specialized chemistry disciplines, but also to the areas of conservation and restoration where chemistry is fundamental tool.
Subject matter
Theory
Examples of the importance of chemistry in conservation and restoration. From the atom to the molecule. Atomic models and chemical bonding. Periodical properties. Solid state chemical bond. Ionic and covalent bonds. Metallic bond.van Der Waals forces. Hydrogen bond. Thermodynamic factors that control the chemical equilibrium. Calculations. Acid-base reactions. Redox reactions. Precipitation reactions. Introduction to chemical kinetics. Order, activation energy and mechanism of chemical reactions.
Practical
The periodic table of the elements. Chemical nomenclature. Measurements, units, and error. Avogadro number. Conversion of the number of atoms in mol. Conversion between mass and mol. Calculation of the atomic and molecular mass. Concentrations. Stoichiometry of chemical reaction. Yields. Electronic configuration and periodical properties. Chemical bond, Lewis notation, VSEPR theory. Introduction to Valence bond theory. Calculations. Acids and bases, definitions; strong and weak acids and bases. pH calculations. Buffers. Solubility product calculations. Redox calculations. Nernst equation. Galvanic Cells. Batteries.
