66684 - Analytical Chemistry and Laboratory

Course Unit Page

Academic Year 2019/2020

Learning outcomes

At the end of the course the student is able to understand and apply the analytical techniques, can identify the chemical equilibria present and evaluate. Influence of chemical parameters on them. He knows the basic statistics necessary for the presentation of analytical data. He knows the potentiometric analytical techniques. At the end of the course, students will be able to recognize the laboratory equipment and describe its use; know how to implement key techniques of volumetric analysis for the quantitative determination of chemical species on the basis of chemical equilibria involved. Will be able to bear with the work of a lab notebook. It will also be able to process and present experimental results using the most appropriate statistical tests.

Teaching methods

The course of analytical chemistry and  laboratory involves front lecture (theory and  introduction notes for the laboratory experiences), numerical calculation on solution chemistry and laboratory experiences. Students should have a bound laboratory notebook for recording all the data at the time of the observation during laboratory classes. The recording of data on loose pieces of paper or in a preliminary note book is expressly forbidden.

Assessment methods

The exams are designed to verify the achievement of the following learning objectives:

principles and chemical analysis procedures and the planning of a simple analytical process;

ability to express the results of a quantitative analytical procedure;

principles of the main chromatographic, electrochemical and spectroscopic techniques;

The exam is done through the specific tests and / or a final exam. The final evaluation will be simultaneously with the Instrumental Chemical Analysis course.
The written non-structured tests consist of solving several problems.
The first will focus on topics of paragraph a).

The second test on the topics of paragraphs b), c) and d).

For written tests during the course will be able to use books, presentations of lectures, calculator and also will need to bring the need for the creation of simple charts. The course tests will be carried out tentatively in the first half of October and in November the second one. The tests provide a maximum score of 33/30 with allocation of points to the individual problems communicated at the beginning of the test.

If the in-course tests were not exceeded their arguments will be the final oral exam. The oral examination will be of type non-structured and will consist in solving problems and in response to questions intended to assess understanding of the topics.

The arguments in paragraph a) and topics of paragraphs b), c) and d) of the program contribute to the 20% and 50%, respectively, regardless of the final result if incurred in the course tests or the final oral test. The final vote is completed by that of the course of Instrumental Analysis that will be worth the restante30%.

The evaluation of the lab course will be based:

 student behaviour (compliance with accident prevention regulations, use of PPE, proper use of glassware and small instruments), +/- 0.75 to mediate with Lab of Analytical Chemistry Instrumental
results of one or more analysis, +0.5 to test if the result has an error less than 3%
laboratory notebook, +/- 0.75

The evaluation, integrated with laboratory of the Instrumental Analytical Chemistry is added to the evaluation of the theory.
