Effusive Volcano

An experiment with balsamic vinegar and baking powder to produce an effusive volcano.
When sodium bicarbonate (baking powder) and acetic acid (the vinegar) react, carbon dioxide (a gas) is released.

This gas can make the vinegar erupt through a narrow opening and allow us to reproduce a volcano.

Carbon Dioxide Production

As we know when sodium bicarbonate (baking powder) and acetic acid (the vinegar) react, carbon dioxide (a gas) is released.


Since carbon dioxide is a gas, as the quantity of gas increases, likely does its volume (PV=nRT).
The reaction of vinegar with baking powder, can fill a balloon as carbon dioxide is released from the reaction.

This is movie about the functioning of carbon dioxide fire extinguishers.
If oxygen is removed by a gas that isn't combustive then the combustion reaction comes to an end.
