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 Method:The assessment of knowledge will be carried out through a mandatory final exam.

   
   


2. 
   

   Exemption from Final Exam: Students who have attended at least 75% of the theoretical classes scheduled for each evaluation module may be exempted from the final exam by taking 2 tests (T1, T2) that will take place throughout the semester during the theoretical class hours, provided that the arithmetic average of the two tests is positive. Taking these tests is optional; however, only students who have attended at least 75% of the theoretical classes scheduled for each evaluation module may be exempted from the final exam. Students who have attended in previous years may take the tests without the requirement of attending theoretical classes. The same applies to students with special status.

   
   


3. 
   

   Final Exam (EX):The regular final exam will consist of two distinct modules corresponding to the material of the tests mentioned in point 2. Students who have taken the tests provided for in point 2 may choose to retake the modules that suit them best in the regular final exam, with the aim of improving their final grade. In this case, the final grade will be obtained with the most favorable score. The final exam of the resit period and the special period will cover all the material actually taught. The final classification will be exclusively obtained from the student’s grade in this exam.

   
   

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.
