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.
