Class Chemistry II

  • Presentation

    Presentation

    The main objective of the UC is to study the molecules and their reactivity, to know the chemical processes that occur in nature, whether naturally, caused by some human interference, or to develop measures that can benefit the environment. The main focuses are the study of the chemical processes in the air, water, soil, pollution, chemical and biological residues; Analyze, remediate and improve nature-related chemical processes. The area of Chemistry allows to understand and explain phenomena directly related to several other sciences, such as Geography, Ecology, Geology, Agronomy, Biology, Toxicology, among others.

    Syllabus

    1-Introduction: Periodic table. Ions in the biological environment. Chemical reactions, stoichiometry, correctness. Solutions Preparation. Chemical Bonding.

    2-Acid-base equilibrium: Factors that influence it (Le Chatelier principle). Strength of acids and bases, type of acids. Buffer solutions. Titrations. Solubility equilibrium. Qualitative analysis. Applications in the study of natural products, biological media

    3-Solubility Equilibrium. Principle of LeChâtelier. Common ion effect

    4-Electrochemistry: oxidation-reduction in biological mechanisms, electrolysis, corrosion.

    5-Chemistry of transition metals. Coordination compounds. Importance of complexes in biological (chlorophyll, hemoglobin). Color and magnetic properties. Spectrophotometry. Effect of complexation on the solubility of a sparingly soluble solid.

    6-Chemical kinetics. Parameters that influence the reaction rate (Chemical catalysts, enzymatic, temperature, concentration)

    7-Thermo-chemistry

  • Objectives

    Objectives

    Acquire a global perspective on the study of chemistry and its interaction with other sciences. Acquire the basic knowledge to apply in specific areas in the areas of Biochemistry, Biology, Health, Environment.

    Develop observation, reasoning and logic in solving problems and drawing conclusions. The theoretical-practical classes alternated with laboratory classes aim to prepare the student to work in terms of behavior taking into account the rules of safety, material handling, observation capacity, reasoning and elaboration of a scientific report.
