The Cool Reaction: An Endothermic Demonstration—ChemTopic™ Lab Activity

firewatch

When most people think of chemical reactions, they think of reactions that give off lots of heat (and light and sound). Reactions that consume heat—endothermic reactions—can be just as exciting. With The Cool Reaction: An Endothermic Demonstration—ChemTopic™ Lab Activity, demonstrate one of the most striking endothermic reactions when barium hydroxide and ammonium thiocyanate solids are mixed together in an Erlenmeyer flask. Available as part of the Thermochemistry—ChemTopic™ Labs digital collection. Click the Price link for digital collection pricing.
