Product Details

Some of the most colorful and interesting compounds to study in chemistry are the coordination compounds. These compounds are usually salts that contain a complex ion; that is, a metal atom bonded to small polar anions, or ligands. In this two-part lab, students will synthesize the brilliant green coordination compound potassium trioxalatoferrate(III) trihydrate, K3[Fe(C2O4)3]•3H2O. In Part 1, the students prepare an intermediate product, iron(II) oxalate. This solid is then converted in Part 2 to potassium trioxalatoferrate(III) trihydrate by oxidation with hydrogen peroxide in the presence of potassium oxalate. The final product is filtered, dried, and weighed. Students use the data to calculate the percent yield. The lab provides the students with experience in synthesis techniques and processes. Includes reproducible student procedure, complete Teacher Notes with sample data and answers to questions, and all necessary chemicals. Complete for 24 students working in pairs.
