LEARNING OUTCOMES

Basic knowledge of chemical equilibria in solution for application to analytical procedures and classical analytical methods based on volume. Learning of practical methods for the accurate carrying out of volumetric analyzes and development of the ability to carry out experiments in the laboratory and to process and present the results.

AIMS AND LEARNING OUTCOMES

The aims of the coourse are knowledge of basic concepts of Analytical Chemistry, as chemical equilibrium, experimental errors and analytical data processing and evaluation. Further aim is to learn how to carry out laboratory analyses, particularly volumetric analyses. 

At the end of the course students will acquire: a) how to solve equilibrium problems, both with mathematical and graphical treatment; b) volumetric analyses theory (titration curves, primary standards and standardization, indicators, experimental conditions influence; c) basic knowledge of data processing end evaluation (experimental errors, accuracy and precision, standard deviation,significance tests); d) the ability to carry out volumetric analyses in the laboratory; e) the skills to process data obtained from their analyses and to evaluate and present them correctly. 

PREREQUISITES

In order to attend lessons and laboratory of this course with good benefits, it is strongly reccommended to have already achieved knowledge of general chemistry and of basic laboratory practice. Students enrolled in Chemistry and Technological Chemistry course must attend all laboratory practice exercise of the General Chemistry Laboratory course before beginning practice exercise lessons.

TEACHING METHODS

Attendance to lessons its not compulsory, but highly recommended. Attendance to practice exercises is compulsory, as well as those lessons where operative details of practice exercises will be illustrated. At the beginning of the course, the dates of these particular lessons will be notified. A special session will be planned to make up missed practice exercises.  

SYLLABUS/CONTENT

Chemical equilibria: acid-base, complexometric, redox and precipitation equilibria. 

Volumetric analysis: basics, titration curves, indicators. Acid-base, complexometric, redox and  precipitation titrations.

Statistical evaluation of chemical data: random and systematic errors, accuracy and precision, standard deviation, confidence interval, signficance tests.

Practice exercises in laboratory regarding volumetric analyses.
