Innovating Science® - Synthesis of a Coordination Complex

Coordination complexes are brightly colored compounds consisting of a central metal atom and ligand molecules, atoms, or ions. Synthesize and purify a lime-green coordination complex called potassium ferrioxalate trihydrate in this multi-step synthesis and optionally analzye the complex via UV-Visible spectrophotometry.

This kit contains enough materials for 15 groups, a Teacher's Manual, and Student Study Guide copymaster.
