Complex ions, coordination compounds and transition metals display some of the most brilliant and beautiful colored solutions. In this two-part experiment, students investigate the properties of complex ions. In Part 1, students form four complexes of the copper(II) ion and the cobalt(II) ion. First, they must identify the chemical formula of each complex ion. They then use the color of the solution to determine the wavelength of light absorbed by each complex ion. Part 2 has students forming solutions of five different complexes of the copper(II) ion. A series of combinations of these solutions are made, and the students determine the relative stabilities of the five complexes based on the precipitates or complex ions formed by the reactions. Includes reproducible student handouts, detailed background information, Teacher Notes with sample data and answers to questions, and all necessary chemicals and consumable supplies.
