COLORED IRON COMPOUNDS: AN EXPERIMENTAL PROPOSAL USING LOW COST MATERIALS

Simone G. Ávila Jivaldo R. Matos

Experimental activities play an important role in the teaching and learning process in chemistry, because it motivates students and promotes the correlation between the activities in the classroom and everyday situations. Based on this context, this work presents an experimental proposal for the synthesis of FeSO4.7H2O using steel wool, aiming at the presentation of concepts such as stoichiometry, oxidation-reduction reactions, the ideal gas law, the intermolecular interactions, solubility, volumetric and equilibrium in aqueous medium, emphasizing the acid-base, precipitation and complexation equilibria. The experiment is designed for both high school students and undergraduate students, with the goal of helping them to develop key concepts in General Chemistry, Inorganic Chemistry and Analytical Chemistry. Moreover, activity may also assist in reflection on reuse of materialsBrazil).
