The reaction of ethyne with chlorine
In association with Nuffield Foundation
Source: © Shutterstock
Try this teacher demonstration with your students to illustrate the spontaneous reaction of ethyne and chlorine. Includes kit list and safety instructions.
In this experiment, students observe what happens when lumps of calcium carbide are added to dilute sulfuric acid in a beaker to produce ethyne gas. As this gas is released, the addition of household bleach to the acid produces chlorine gas as well.
