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 understand the importance of pH.

Theoretical component:
1 - 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.
2 - Chemical bonding: Octet rule. Covalent bonds, ionic and metal. Nomenclature of ionic compounds.
3 - 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.
4- Acids and bases: Bronstead-Lowry acid systems; Autoionization of water; Calculation of the concentrations of the hydrogen ion and the hydroxide ion; Criteria for acidic, basic and neutral solutions; The concept of pH; Solutions of strong acids and bases; PH measurement; Exemplification of pH measurement of solutions with pH meter, and universal indicators.
5- Organic Chemistry: Saturated hydrocarbons; Alkanes; Cycloalkanes; Nomenclature of saturated hydrocarbons; Nomenclature of cycloalkanes; Functional groups; alcohols and ethers; Aldehydes and ketones; Carboxylic acids; Esters; Amines; Amides; Polymers.

Practical component:
Practical work # 1 - Lab work for the ambiance of students to chemistry laboratory, knowledge of commonly used material, the use of analytical balances and familiarization with the descriptive statistical data analysis.
Practical work # 2 - laboratory work for the implementation of the stoichiometry of knowledge in the preparation of solutions for weighing, dilution and from concentrated solutions.

Evaluation Methodology
Continuous evaluation in 3 tests related to the theoretical component and 2 reports of the laboratory work related to the practical component.
The final assessment adds the values obtained in both components and requires 10 values for exam exemption.

Method of interaction
Theoretical classes where the theoretical fundamentals are taught and practical laboratory classes where will be carried out tests with laboratory material for the measurement of volumes, of weighing of masses and preparation of solutions.
