Avantor can help with a robust line of safety products and personal protective equipment -- from waste bins to safety signs. This demonstration can be used as an introduction to the idea that different oxidation states of transition metal ions often have different colours, and that electrode potentials can be used to help predict the course of redox reactions (via the anticlockwise rule or otherwise). If it is allowed to stand for a long time, the solution eventually turns blue as the air oxidizes it back to the vanadium(IV) state - VO2+ ions.
