4.5 ECTS; 1º Ano, 1º Semestre, 30,0 T + 30,0 TP + 2,0 OT

Lecturer
- Manuel Alberto Nogueira Henriques Rosa

Prerequisites
Not applicable.

Objectives
Development of capacities for the understanding of the themes of general chemistry and its application to the processes of conservation and restoration of works of art. Particularly in laboratory work to prepare solutions, measure and identification of salt anions.

Program
Theoretical component:
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: Theoretical component with three written tests (12 points) and practical component with two practical work reports (8 points). The final grade is obtained with the sum of the evaluation obtained in the two components. Minimum grade for the theoretical component is 5 points and the practical component is 3 points. Exemption from exam with 10 points.
Exam assessment: Theoretical component with a written test assessed at 12 values, or practical component in reports assessed at 8 values, students pass if the sum of the assessments in both components is equal to or greater than 10 values.

Method of interaction
Theoretical classes where the theoretical fundamentals are taught and practical laboratory classes where will be carried out measurement of volumes, weighings, preparation of solutions and identification od anions.
