Students should understand general chemistry and its application in the graphic processes as well as the variables of chemical processes. Development of skills in laboratory practice of Chemistry, by performing some practical works.

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. Atomic mass, mole and molar mass. 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: Balance of chemical equations; yeld of chemical reactions. Solutions and molarity. Preparation of solutions by weighing, diluting and from concentrated solutions.
4 - Chemical equilibrium: Bronsted-Lowry and Ahrrenius acid-base systems. The auto-ionization of water. The concept of pH. PH measurement: indicators and meters. PH electrode meter. The reference electrode. Operation of the combined electrode. Temperature effect on the pH measurement. Calibration of the pH meter.
5 - Oxidation-reduction: Writing and balance of redox reactions. Standard electrode otentials. Spontaneity of redox reactions. Electrochemical cells.
6 - Organic Chemistry: Alkanes and Cycloalkanes. Nomenclature of saturated hydrocarbons. Nomenclature of cycloalkanes. Functional groups: Alcohols and ethers; Aldehydes and ketones; Carboxylic acids; Esters; The amines; Amides; polymers.
7-Chemistry of paper, inks and toners: main aspects relevant to their behavior and use.

Practical component:
1-Measurement of volumes and masses of liquids.
2-Preparation and dilution of solutions.
3-Standardization of solutions.
4-Determination of the pH of the paper.
5-Study of the revelation variables.

Evaluation Methodology
Students who do not complete the five experimental works of the curricular unit and their written reports will be excluded from the exam evaluation, and the accomplishment of these tasks is considered indispensable.

In the evaluation in the period of frequency and in the period of exam will be carried out a written test with consultation of Periodic Table and Ion Table.

In the evaluation in the period of frequency and in the period of exam the final classification is obtained through the weighting between the classification obtained in the written test and the classification obtained in the experimental work, 60% of which is attributed to the written test and 40% to the works. The minimum grade of the written test that allows approval is of 7 values.
