According to Steve Spangler Science, mixing vinegar and baking soda starts a chemical reaction that produces carbon dioxide, or CO2, and water. The chemical names of the two ingredients are acetic acid, which is the vinegar, and sodium bicarbonate, which is the baking soda.
When vinegar and baking soda is mixed in a lunch bag or similar container, the carbon dioxide produced fills up the container. The container bursts or “explodes” when there is no more space for the gas in the bag or container.
In Scientific American’s version of the experiment, a film canister gets launched into the atmosphere like a rocket. The gas builds up in the canister until the lack of room pressurizes the closed canister causing it to pop open and fly into the air.Learn More
In the event of a hydrochloric acid spill, baking soda is poured on the acid to prevent damage to surfaces. Baking soda is a weak base; when added to hydrochloric acid, it causes a neutralization reaction so the hydrochloric acid no longer causes damage to other materials. In the event baking soda is not available, the spill is diluted with copious amounts of water.Full Answer >
Mixing hydrogen and oxygen equals water, but at room temperature and normal pressure this happens extremely slowly; an energy source, a catalyst, is needed to start the chemical reaction. However, hydrogen is extremely flammable and explodes even in the presence of a lighted match or a spark, so attempting this is not advised.Full Answer >
When baking soda and vinegar combine in a container with a balloon placed over the opening, one of the resulting materials is carbon dioxide, which fills up the balloon because it has nowhere else to go. Water and sodium acetate are also created from this combination. The mouth of the balloon needs to have a good seal in order to prevent the carbon dioxide from escaping.Full Answer >
Mixing toilet bowl cleaner and aluminum foil causes a chemical reaction that produces hydrogen gas. According to Newton Ask a Scientist, the typical reaction with this mixture is 6HCl + 2Al = 2AlCl3 + 3H2(gas).Full Answer >
