Usually sensitive ones say on the side what temperature to store them at on the side. For flammable ones tho, you need a special “fume safe” fridge that cannot accidentally have the internal wiring spark and contact any vapors that may be around.

[@ChemicalForce]

thank you :D

[@jpolowin0]

My second Ph.D. research project (the first one was discarded after 4 months) started with converting Fe(CO)5 to the dark green Fe3(CO)12 -- lovely almost-black crystals. That was almost 30 years ago, so I don't recall the details, but I seem to recall that photolysis was one of the steps. The Fe3(CO)12 was then reacted with thiophene (C4H4S) with a reflux/Soxhlet extractor to give a nifty organometallic compound, Fe(C4H4)Fe(CO)3, with a dark-metallic deposit of FeS on the vessel walls. It was one of the smellier projects in the lab, which was already notable for some unpleasant organometallic-related odours. Though the work was done in a fume hood, traces clung to my gloves and the arms of my lab coat. Good times... I really miss doing that stuff. One of my old "magic with chemistry" books described preparing ferrous oxalate, then thermolysing that to give CO2 and what was supposed to be pyrophoric iron. I never had much success with it; the resulting iron never did anything more than smouldering a bit, instead of the expected stream of sparks as it was poured out of the test tube.

Like I said in my other comment, short videos are in extremely high demand on this site.

Worked with this compound when at university, working in a research lab. Quite dangerous compound, but nowhere near its cousin nickel tetracarbonyl, aptly name "the gas of death". This one is much more volatile and decomposes at much lower temperatures, AKA in the lungs...

[@Mr.Nichan]

I kind of like the unpacking part, just to see how chemicals are packed up. One thing I might slightly disapprove of though, is that I think you might slightly overuse slow motion on the pyrotechnics. More specifically, I like to be able to see all the reactions at least once in real time, and I think sometimes you only ever show them in slow motion. The slow motion is still great, though, and also Fe(CO)5 is one of my favorite chemicals (the idea of it anyway), even though pretty much all I knew about it before this video came from Wikipedia and I don't actually that much about it.

[@JoshStLouis314]

Decomposition of iron (II) oxalate also makes quite pure iron, though less useful because the iron is pyrophoric 😏🔥

I think, if the packaging is something we have not seen, it's nice to see it. If we have seen it many times, there is no point. I think most people would agree - as long as it is informative and gives something new.

Cool video. I would have never known about these reactions and even half of thsese chemicals if I didn't see your channel. Waiting for more. However, the reaction of tert-butyl hydroperoxide with Mn2O7 doesn't show the aggressive behavior of tert-butyl hydroperoxide as reaction of this oxidizer with acetone looks similar imo. I would like to see that on your channel as a reference to how the reactions presented by you look in real life but it seems to trivial to be on this exotic channel.

[@sargon6000]

6:45 Wait, why isn't that pure iron pyrophoric? If you decompose iron oxalate, the resulting metallic iron particles obtained immediately ignite in contact with air. What's the difference here?

[@arahatchikkatur1906]

Most likely due to the size of the particles since the iron formed by decomposition of iron oxalate are smaller and hence react more violently with oxygen in the air.

Be careful with the Fresnel reflections of the laser off glass both into your eyes and into the camera. It will burn both. If you got that as a cheap laser pointer off of ebay it's NOT the 5 milliwatts it says on the label. It's 40-60 milliwatts. I tested it. Even the specular reflections are powerful enough to cause permanent damage.
