This video describes how to complete a chemical reaction that involves an orange to black color change. The experiment can be done using materials easily obtained in stores. The reaction is strikingly similar to the Old Nassau Reaction, but does not require the use of mercury reagents. A full explanation of how to carry out the experiment, and also the chemistry involved is included.
