Vanadium Oxidation States - A Most Colorful Experiment

This chemistry experiment shows you how to produce red, orange, green, yellow, blue, and purple all in one solution, all the colors of the rainbow - without dyes or indicators. How is that possible? We show you how to produce the amazing oxidation states of vanadium in one of the most exciting experiments we have ever done. You can find the complete procedure and safety notes in Vanadium Oxidation States Experiment.
