Analytical Chemistry

Presentation

This curricular unit belongs to the curricular plan of this 1st cycle degree, whose concepts taught are important for the acquisition of knowledge of subsequent curricular units.

This course aims to provide students with fundamental knowledge of the fundamental aspects of chemical processes associated with the different steps of a chemical analysis; the description and scientific basis of the different processes that make up a chemical analysis; and identifying and understanding the interaction of analytical chemistry with other areas of human activity (environmental, industrial analysis, ...).

Syllabus

- Analytical Chemistry: objectives and methods. "Traditional" methods and instrumental methods. Definition and applications. Sampling. Interference.

- Gravimetry: Solubility and formation of precipitates. Contamination of precipitates. Gravimetric analysis operations.

- Volume: equivalence point and end point. Accurate measuring of reagents. Detection method. Volumetric type.

- Volumetry acid-base: General considerations. Equivalence point versus point end. Determination of the end point.

- Volumetry of complexation: complex ion Formation. Mono- and poli-ligands. Indicators. The EDTA titration techniques: direct, inverse, titration by offset, indirect and masking.

- Volume of precipitation: Argentometric Processes. Mohr, Volhard and Fajans.

- Volumetric oxidation-reduction (redox): Nernst equation. Titration curves. End point detection. Permanganometry and dichromatometry. Iodimetric methods.

Objectives

- Know the scope and essential concepts of analytical chemistry

- Know the basics and knowing how to apply techniques of gravimetric

- To know and learn to apply the principles and the volumetric techniques (acid-base, complexometric, redox, precipitation)

- Knowledge and practice laboratory of analytical chemistry (gravimetric and volumetric techniques) with application in real samples (water, soil)

- Knowledge of the processes of pollutant transport: transport and re-concentration of neutral organic compounds and metal ions and their analytical procedures

Teaching methodologies and assessment

The contents are taught in lectures and practical lessons. The lectures will be presented and developed the concepts referred to in the program. The practical lessons, students will perform laboratory work where the objectives are not only illustrating concepts acquired in lectures, but also familiarize them with current utilization techniques in analytical chemistry and its interpretation of results vis-à-vis legislation in force.

Evaluation: Continuous [2 written tests 70% + practical works 30%] and by final exam [100%], in accordance with the ULP Knowledge Assessment Regulations.
