Fuming nitric acid is defined as having a concentration of HNO3 greater than 86%. This is much higher than the conventional 68% of common lab nitric acid. The reaction between the nitric acid and the nitrile and latex gloves is extremely exothermic and violent. It is often recommended to avoid using gloves altogether when working with fuming nitric acid unless resistant gloves are available (e.g. butyl rubber gloves). Regular concentrated nitric acid is still not good to use with latex gloves. Latex offers little to no protection. Nitric acid can quickly penetrate the glove and then irritate skin. Fuming nitric acid is not nearly as common and it is used in much fewer reactions. For example, for the synthesis of high explosives. The high concentration of HNO3 is required in order to nitrate a molecule several times. For example, TNT, or tri-nitrotuluene, is prepared using fuming nitric acid. It is possible to di-nitrate it using concentrated nitric acid, but the third nitration is unlikely to occur, so yield will be zero or uselessly low. ... https://www.youtube.com/watch?v=aBVdGGml6bU

A while ago, I ate capsaicin, which is basically pure spiciness. However, capsaicin is hydrophobic, so it had a very hard time dissolving on my tongue. However, if I take capsaicin and dissolve it in alcohol, it's technically is less concentrated, but it should be a lot spicier...

Note: The MnO2 that i used was likely contaminated with A LOT of carbon. I think if more pure MnO2 were used, the yield would be a lot better. In this video, we whip up some bromine using sulfuric acid drain cleaner, MnO2 from batteries, and sodium bromide pool solution. At around 8 minutes, it should be sodium bisulfate not potassium! I made a mistake.

The synthesis of iron (II) sulfide involves reacting 1 equivalent of sulfur with 1 equivalent of iron. The reaction is initiated by a hot glass stirring rod into it. It is an extremely exothermic reaction. This is an interesting reaction to use as a demonstration, but the product is useful. The Iron (II) sulfide, or FeS, can be reacted with hydrochloric acid to produce hydrogen sulfide gas. This is a very useful gas, but it is extremely toxic. ... https://www.youtube.com/watch?v=NxAeQneITNA
