Objectives
Development of skills for understanding general chemistry topics and their application to the conservation and restoration of artworks, particularly in laboratory work involving the preparation of solutions and the measurement and identification of salt anions.
Program
Structure of matter: properties of matter; extensive and intensive properties; density and temperature (scales). Classification of matter: mixtures and pure substances. The atoms. The discovery of subatomic particles. Atomic number and isotopes. Ions. Periodic table. Periodic variation of metals, non-metals and metaloids. Electronic configurations and the periodic table: variation of atomic properties.
Chemical bonding: Octet rule. Covalent bonds, ionic and metal. Nomenclature of ionic compounds.
Stoichiometry: atomic mass, mole, molar mass and chemical reactions. Hit chemical equations; solutions and molarity. Preparation of solutions for weighing, diluting and from concentrated solutions.
Salts: What are salts?; Soluble salts and insoluble salts; Hygroscopy and deliquescence; Importance of the salts in the patrimony; Movement of salts on the walls of a building; Identification of carbonates, chlorides and sulfates by chemical tests.
Evaluation Methodology
Continuous assessment consists of three written tests (T1, T2 and T3) and two laboratory reports (P1 and P2), each graded on a 020 scale. The final mark is the average of the five assessments, and students must obtain a minimum of 10/20 to pass.
Final mark (continuous assessment):
(T1+T2+T3+P1+P2)/5
Attendance in laboratory classes is mandatory, and students are required to prepare the laboratory reports in groups.
For the Examination, Resit Examination, Working Student, and Special Assessment periods, students are assessed through a theoretical examination (T) graded on a 020 scale. The final mark is calculated as follows:
Final mark (examination):
T*0,6+P*0,4
where P is the average mark obtained in the two laboratory reports.
Students pass if they obtain a final mark of 10/20 or above.
