Objectives

It is intended that this course gives the student the ability to understand and describe the various processes of separation usually used in chemical analysis, identifying their common aspects and showing their particular characteristics that allow them to perform certain specific separations. Assimilation and integration of concepts and features to provide a comprehensive view of the processes of separation based on the heterogeneous equilibrium, in particular, precipitation, solvent extraction, ion exchange and chromatography. The second aim is to provide the concepts of potentiometry.

Program

The contents of the course are divided into five major topics: 1 Introduction to chemical analysis, qualitative and quantitative analysis, chemical and instrumental methods. Collection and processing of data. 2. Systematic treatment of simultaneous chemical equilibria. 2.1 Equations of material balance, balance of electrical charge and balance of protons. 2.2 Application to acid-base reactions, complexation and oxidation-reduction. 3 Heterogeneous equilibria in analytical chemistry, precipitation, partitioning and solid-gas equilibrium. 4 chromatographic separation processes. General Theory. Chromatographic models. Adsorption chromatography, partition, ion exchange, affinity, and exclusion. Gas chromatography. 5 ion selective electrodes and potentiometric methods.

Teaching methods and learning activities

The teaching of analytical chemistry 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 Type 1 The assessment will be done through distributed evaluation with final exam required. 2. Distributed Componentof the evaluation: 2.1 The distributed component of the theoretical and theoretical-practical assessment consists of student participation in class T and P, in problem solving skills and in responding to questions . It also involves the classification of the student's participation in the forum for questions and answers in active e-learning platform. This evaluation component is optional. 3 Final exam (EX) The final exam will consist of a modular writing exercise consists of two parts: Part I:Written exercise with response closed. Students can dispense this part of the examination provided that the grade obtained in the distributed component of assessment is not less than 9.5 (scale of 0 to 20). Estimated time: 45 min Weight classification of the exam: 30% Minimum grade: 5.0 values (range 0 to 20) Part II: Written exercise with open-response. Estimated time: 120 min Weight classification of the exam: 70% Minimum grade: 7.0 values (range 0 to 20) 4 Final The final grade will be calculated using the algorithm: 0.30 * Part I examination or assessment of distributed component + 0.70 * Part II examination. Note: for students who obtain a positive note on distributed component evaluation and choose to carry out part I of the examination it will be considered the better score.

Classification improvement

The distributed classification can not be improved. The final mark can be improved in the second possibility of the final exam
