Objectives

This CU intends to supply concepts and abilities to the understanding and explanation of the basic principles of analytical chemistry and its importance in the pharmaceutical sciences scope.It´s intended to assure that students dominate the essential questions related with the different types of chemical equilibrium: solubility, acid-base, oxidation-reduction and complexation, its application in a view point of quantitative analysis in the areas of knowledge presented in MICF. One expects the use of these knowledge in a theoretical and laboratorial perspective. As learning outcomes it is expected: interconnection capacity between knowledge and basic techniques of analytical chemistry and other fields of knowledge present in the MSc in PS; capabilities for manipulation of the concepts presented; independent and analytical reasoning; ability to apply new chemical concepts in solving practical problems; ability to present their arguments and solutions in a clear and precise way.

Program

Theoretical component:

The central role of Analytical Chemistry. General steps of a chemical analysis. Classic analytical methods of Analytical Chemistry: gravimetry (by chemical precipitation) and volumetry (involving acid-base, precipitation, complex formation and redox reactions). In each topic the theoretical and practical aspects are presented. All the themes presented are accompanied with practical examples in the scope of pharmaceutical sciences.

Laboratorial component:

Concepts of elementar statistics of results of analysis (accuracy and precision; absolute and relative error; fortuitous and systematic errors) and the calculation of the precision of indirect measurements. It involves also laboratory works, resulting from pratical applications of theoretical concepts and from the Portugiese pharmacopea

Teaching Methodologies

Theoretical classes, with the help of available audio-visuals. The introduction of concepts must include the reference to practical examples, and the presentation of the resolution of theoretical and practical exercises. Where necessary it resorts to the use of the board.

Practical Classes – dedicated to resolving exercises involving the application of concepts, clarifying any doubts and expanding specific themes.

Laboratory classes – carrying out the laboratory work of qualitative and quantitative chemical analysis (volumetry and gravimetry). The work is carried out individually and in some of these tasks, the presentation of a report is compulsory. Besides the students have to do a presentation about one of the theme explored in the classes.
