A carbohydrate is carbon plus water. With The Carbon Soufflé: Removing Water from Sugar Demonstration—ChemTopic™ Lab Activity, remove the water from a carbohydrate, and whip up a carbon “soufflé” by reacting sugar with sulfuric acid. The mixture turns brown and then black before expanding and solidifying and fill the room with the odor of caramelizing sugar. Available as part of the Chemistry of Organic Compounds—ChemTopic™ Labs digital collection. Click the Price link for digital collection pricing.
