Objectives and competences
Provide fundamentals of classical volumetric and gravimetric analytical methods, based on acid-base, oxidation-reduction, precipitation and complexation reactions.
Understand the analytical processes and associated chemical reactions and the processes of detection of equivalence points.
Calculate concentrations of chemical parameters in different types of samples, and expressed in different units.
Interpret the results obtained and assess whether they are credible. Estimate the precision and accuracy of chemical analysis.
Prepare a report of a chemical analysis.
In view of the analytical problem that is faced, select the most appropriate methodology to solve the problem in question.
Handle, in a scientifically correct, expeditious, and safe way, laboratory material related to volumetry and gravimetry.
Teaching Methodologies
Lectures common to all groups, with great interaction with students, accompanied by theoretical-practical classes to solve application problems, carried out in class, usually with a number of students less than 20.
Laboratory classes (#6 works), involving the manipulation of the analytical methods discussed in the theoretical classes.
