Inflating Glove

We inflate a rubber glove using the gas produced during a neutralisation reaction. Bicarbonate of soda is added to vinegar in a beaker covered by a rubber glove and it expands. The gas is used to extinguish a flame, showing that it is carbon dioxide. Chemistry - Reactions - Learning Points. A gas being produced is a sign of a chemical reaction. Acids and bases react in neutralisation reactions. Carbon dioxide is denser than air. Combustion requires oxygen. A Twig Experiment Film. Let students experience real experiments in lab conditions anywhere, from setup, method all the way through to analysis and real-world application.
