The “Chemistry of Color” was the American Chemical Society (ACS)’s theme for the 2015 National Chemistry Week. Presentations were staged across the US. The local section of the ACS joined forces with the Nasher Museum of Art (Duke) to put on a chemistry event for more than 600 attendees. Representatives from industry and academia, including Duke Chemistry Outreach, oversaw a variety of activities that addressed this theme. It was a massive undertaking to have both a chemical stage show and a hands-on activity room, all involving color.
We had a variety of colorful demonstrations, many of which have been featured in Chem 13 News. These demonstrations mentioned in past issues will be posted online at the Chem 13 News website, under supplemental materials for the March 2016 issue. In this issue we will discuss the Chemical Rainbow. The Landolt Iodine Clock Reaction and UNC Blue to Duke Blue demonstrations will be presented in upcoming issues.
