Objectives

It is intended that this course gives the student the ability to understand and describe the various analytical procedures  usually used in chemical analysis, identifying their common aspects and showing their particular characteristics that allow them to perform certain specific analytical applications. Assimilation and integration of concepts and features to provide a comprehensive view of the processes based on the heterogeneous equilibrium, in particular, precipitation, and solvent extraction. Finally a full insight about volumetric analysis will be given.

Learning outcomes and competences

The students will develop the ability to understand and apply the various analytical procedures usually used in chemical analysis, identifying their common aspects and showing their particular characteristics that allow them to be useful in certain specific analytical applications. They will assimilate and integrate the concepts and features to allow them to have a comprehensive view of the processes based on the heterogeneous equilibrium, in particular, precipitation, and solvent extraction. Finally they will get a full insight about volumetric analysis and its applications.

Teaching methods and learning activities

The teaching takes place through lectures and theoretical-practical classes. Lectures are exhibition spaces for exposure of the themes of the program, using the visual aids available. The practical classes are spaces dedicated to problem solving, application of concepts learned and treated in the lectures, to clarify doubts and for critical analysis of the final result.

Eligibility for exams

Student attendance to the practical classes is mandatory. Those students whose attendance is lower than 3/4 of the classes planned are considered without attendance.

Calculation formula of final grade

1. Evaluation
 The assessment will be done by final exam.
2. Final Exam Exemption
The student may waive the final exam by performing two tests (T1, T2) during the semester, provided the arithmetical average of the two tests is positive. The conduct of these tests is optional.
3 Final exam (EX)
The final exam of normal season will consist of two independent modules corresponding to the subject of the tests referred to in  2 .. Students who have chosen to perform the tests may still choose to do the modules in final exam. The final score of this examination will be obtained through the arithmetical average of the marks obtained in the two modules. For students who have chosen to perform the tests and then repeat the module(s) in final exam, the classification considered will be the most favorable. In the supplementary exam period and special season the exam will be unique  encompassing all effectively taught matter. The final rating is obtained exclusivelly  from the score of the student in this examination.

Examinations or Special Assignments

Realization of two tests during the semester.

Special assessment (TE, DA, ...)

The assessment for students with special status will be done on the final exam. However, they may choose to perform the tests mencioned and follow the evaluation process described therein.

Classification improvement

The improvement in classification can be achieved by performing final examination for this purpose.

Observations

No frequency waiver to practical classes.
