Too Hot to Handle? Hydrogen Reacts with Oxygen on Palladium Foil

The reaction of hydrogen and oxygen gases to form water is well known to be an exothermic reaction. That reaction can occur by first absorbing the hydrogen into palladium metal, and then placing the resulting palladium hydride into contact with oxygen in the air. Infrared and visible light videos were recorded for this process involving palladium foil, and the Green Chemistry and safety aspects of these activities are considered.

Thermal Paper as a Polarity and Acidity Detector

Thermal paper such as that used for point of sale receipts typically functions by darkening when exposed to heat. The pigment system used in this paper also darkens when exposed to solvents of intermediate polarity and acids. This enables thermal paper to be used as an inexpensive sort of indicator paper for a variety of demonstrations.

Seeing Chemistry in a Different Light—FLIR Thermal Cameras in the Classroom

Before trying to use a piece of equipment, it’s worthwhile to have a basic understanding of how it works. To put it simply, FLIR cameras primarily deal with the infrared part of the EMR spectrum. The camera detects infrared energy and converts it into an electrical signal, which is then processed to produce a thermal image on a video monitor.
