Carbon Dioxide Gas Production
Carbon Dioxide Gas Production is what happens when two substances mix and release carbon dioxide gas, like the fizzing you see when baking soda meets vinegar.
The fizzing in your sink when you pour baking soda down it and add vinegar shows carbon dioxide gas being released. The two substances mix and react, forming a new gas that bubbles up quickly. You can see the bubbles rise and pop at the surface. The same thing happens inside any reaction that produces carbon dioxide gas.
Explaining carbon dioxide gas production by grade level
When you drop baking soda into vinegar, tiny bubbles form right away. Those bubbles are filled with a gas called carbon dioxide. The gas is lighter than the liquid, so the bubbles float up and pop at the top. If you put raisins in the cup, bubbles stick to them and carry them up to the surface like little life jackets.
Projects that explore carbon dioxide gas production
When an acid meets a base, the two react and release carbon dioxide gas. That gas forms bubbles that fizz and rise into the air. A baking soda and vinegar volcano shows this reaction clearly because you can see and hear the gas escaping.
Gas bubbles can change how heavy something seems. A drop of water is denser than oil, so it sinks. But when carbon dioxide bubbles attach to that drop, they make it lighter than the oil. The drop floats up.
