Except I usually grab sodium perchlorate. The potassium chlorate is a rich source of oxygen gas, while the gummy bear is a source of carbon. Understanding: Our experience with salts is that they are solids. Filter By Category Flaired Users How To Make Gifs Please read for a comprehensive guide on gif making. Thus, it may be simply placed in a test tube and heated over a burner.
At room temperature and pressure, the salt exists as a solid. Have the students ignite the methane bubbles as they rise to the ceiling. This chemist knows what he's talking about. It is more along the lines of two college science majors trying to come up with an experiment that will entertain a room full of high school freshman, and possibly plant the seed for a future scientist at the same time. In Finland it was sold under trade name Fegabit. Molten potassium chlorate is an extremely powerful oxidizer and will spontaneously react with many common materials.
It would decompose and turn molten. The hygroscopic and slightly weaker sodium chlorate is sometimes used as a safer and less expensive substitute for potassium chlorate. Add a gummy bear to the boiling tube. She leaves the threat, Tell us what we want to know or this will happen to you, implied. Spill it onto your skin, and it would leave a terrible burn. It may cause an explosion. A fire on the space station Mir was also traced to this substance.
Set up the ringstand-clamp-test tube assembly behind a safety shield in front of the class. Potassium chlorate is used also as a pesticide. Any link post that is not in one of these formats will be deleted. Lets burn gummy bears to produce electricity!! So on to the procedure! Potassium chlorate is used in chemical oxygen generators also called chlorate candles or oxygen candles , employed as oxygen-supply systems of e. It can be used as a propellant and as a source of heat to make colored fires.
NurdRage has a great tutorial on making with laundry bleach and sodium-free salt i. Make sure that this set up is done in a Fume Hood. The reaction produces a sweet burnt smell. In rare cases, exceptions may be made by the moderators if a post is exceptionally intriguing and relevant to discussion in order to maintain quality standards. Do not do this experiment with a small or short test tube as molten pieces of bear will fly out while the reaction progresses. Good christ, that was terrifying for a moment. The reason is due to the large formal charge on the chlorine atom.
Take the chemical formula of the gummy bear to be glucose sugar, C 6H 12O 6. . Heat the solid salt until it becomes molten, demonstrating the high melting point of ionic solids. Chlorate propellants must be used only in equipment designed for them; failure to follow this precaution is a common source of accidents. When you heat up ice passed 0C, it melts into water, a liquid. When used in explosives as an oxidizer, the explosive is low order meaning it burns rapidly rather than explodes.
Not because it was relevant or anything, he just felt like doing it. Sugar is a molecule composed of carbon, hydrogen and oxygen only. It won't work with other oxyanions because they the central atoms aren't electronegative enough to pull electrons away from the oxygens. I crept up into the barn. The reaction is quite violent and produces a great deal of heat, white smoke, and pinkish-purple light. Potassium chlorate mixed with charcoal is a common component of fireworks as it is a good source of heat and gas. Stand behind the safety shield and carefully drop one gummi bear into the test tube using tongs or forceps.
It depends on how it reacts. This is due to trouble categorizing a post which often has multiple gifs that don't fall under one category and leads to a misleading post and confusion. The reaction is as follows:. Due to our subreddit's size and variety of interesting gifs, over time this we have grown to be accommodating to other types of chemistry, physics and biology related gifs those who would just like to view one type may use our filters on this sidebar. A similar demo can be done by blending sugar and potassium chlorate then using concentrated sulfuric acid to initiate the reaction. The ionic attractions are far greater than the force of collisions between atoms and molecules at room temperature, so salts are typically solids. For example a post featuring a can being smashed or the motion of a pendulum will be removed.
Clean up is not the easiest because there are charred bits stuck to the test tube. After it's hot enough, the roach is dropped in and consumed by flames until there's nothing but. A poor defenseless gummy bear, a test tube full of liquid potassium chlorate, and a couple of slightly mad scientists; seems like the perfect set up for some absurd B-movie horror flick, does it not? And what better way to achieve that, then a rapid oxidation reaction? Everything else looks like absolutely nothing is happening, and therefore that is why most people think that chemistry is dumb. We managed to make some small rocket engines using sugar and charcoal powder. Many salts are found to be soluble in water. John Straub's lecture notes Gummy bear exploration of molten salt world ends in tragedy A salt of potassium chlorate is melted. You class will remember it for years! Take some , a and add some heat.
Clamp the test tube in place at an approximately 45Â° angle. The gummy bears were screaming. Both Gummy Bear and boiling tube sacrificed for this demonstration. Of course this occurs at a significantly higher temperature, but the process is pretty much the same as far as we have to be concerned. At least there's no screaming this time. I guess potassium salts have similar properties, and we got similar results to the video when we combined it with any kind of fuel. Molten potassium chlorate is very nasty stuff.
