Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)
General objectives:
Give the student a broad view of Chemistry within the framework of their basic scientific training (UC of Basic Science).
Specific objectives - skills (knowledge, skills and attitudes):
• Determine the basic knowledge about Oxidation-reduction, essential to the understanding of the analytical techniques of determination of environmental parameters (UC of Environmental Analyzes);
• Determine the basic Oxidation-Reduction knowledge needed to understand treatment processes involving redox reactions, eg. Advanced Oxidation technologies (UC of Supply Water Treatment);
• Understand the environmental relevance of Oxidation-Reduction in natural waters.
• Determine kinetic knowledge essential to the design of chemical and biological reactors;
• Be able to experimentally determine the kinetic law of a chemical reaction (in the laboratory);
• Understand the degradation kinetics of substances in the Environment;
• Know the main metals and ligands contaminants and naturally occurring in waters and soils;
• Understand the environmental relevance of complex balance in natural waters and soils;
• Understand the relationship between speciation, solubility, bioavailability and metal toxicity;
• Be able to determine the concentration of the various species / complexes in equilibrium and draw conclusions regarding the bioavailability in the environmental conditions;
• Be able to perform complexometric titrations, necessary for the determination of environmental parameters (Environmental Analysis CU).
• Make known the nomenclature and reactivity of organic compounds (at an introductory level).
• Develop the scientific and experimental spirit, the ability to organize and analyze information and work as a team.
Syllabus
1. Oxidation-reduction and Electrochemistry
Redox reactions. Oxidation number. Correlation of redox equations. Standard reduction potential. Reference electrode. Galvanic and electrolytic cells. Cathode and anode. Semi-oxidation and reduction reactions. Electromotive force of the cell. Nernst equation.
2. Chemical Kinetics
Speed of reaction. Kinetic law (and partial orders). Time evolution of the concentration of a substance. Half-life time. Effect of temperature, activation energy, Arrhenius equation.
3. Complexation
Geometries of the complexes, oxidation state of the metal; isomerism. Polydentate ligands and chelating effect. Environmental importance of chelates.
Balance of complexation. Stability constants (Ki) and global constants of formation (βi). Calculation of species concentration in equilibrium.
Speciation and Complexation in the Environment: solubilization of metals (and bioavailability). Metals and ligands of natural occurrence and contaminants.
4. Organic Chemistry
Main organic pollutants. IUPAC nomenclature of organic compounds. Functional groups.
Reactivity and physical properties of the main families of organic compounds: alkanes, alkenes and alkynes, alkyl halides, alcohols, aldehydes and ketones, carboxylic acids and derivatives
Teaching methodologies
IMPORTANT NOTE:
The UC Chemistry II-LEA will run in the academic year 2017/18 under a tutorial regime. Teacher: Carla Gamelas Reis
Assessment methodologies and evidences
Assessment Type Distribution assessment with final exam Assessment Components
The student can choose a continuous evaluation or by exam:
1. If you wish to be evaluated by examination, you will provide proof in the normal time or at the time of appeal, obtaining approval if you have a grade of 9.5 or higher.
2. If you choose continuous assessment, the student will perform 2 tests during the semester:
1st test: 7th week
2nd test: 15th week
To pass, you must have a grade equal to or greater than 8.5 val. in each test and an average greater than or equal to 9.5 val. in the 2 tests.
The approval in the discipline implies 9.5 values of theoretical grade and 9.5 values of laboratory grade.
The laboratory grade has a weight of 30% in the final grade.
Attendance system
Without the attendance of the laboratory classes and delivery of the respective results sheets / questionnaires, the student will not be able to obtain approval in the CU. MAX is allowed. 1 lack of laboratory work.

Observations
-The students who hold Student Worker status must communicate this fact to the responsible teacher (carla.gamelas@estsetubal.ips.pt), in the first week of classes.
-Date of doubts: Tuesday, at 10:30 a.m. Thursday at 12:30 p.m. Students wishing to ask questions should send the teacher an email in that sense (carla.gamelas@estsetubal.ips.pt).
-Slides, Worksheets and lab protocols, you Moodle
