We have presented a simple cost-effective cyclic voltammetry experiment for the quantification of over-the-counter iron supplement tablets. This experiment is suitable for both junior and senior undergraduate chemistry students. Some of the learning outcomes presented include the introduction to cyclic voltammetry and the basic features of a reversible cyclic voltammograms. Other learning outcomes include statistical evaluation and presentation of experimental data. The low sample volume requirement using the method of standard addition to a single solution is also highlighted.
