Your videos remind me of chemistry at school 35 years ago, before 'health and safety" sucked the fun out of it... Never forget when my teacher "reconstructed" the Hindenberg disaster by filling a condom with hydrogen for one demonstration 😂
@@xenoxaos1 That's the problem exactly, I WANT precision. "Just do whatever" doesn't work with me. I'd rather work with moles than dashes or sprinkles.
Yeah, i recommend getting a small oxy/acetylene torch for making ampules. The cost is fairly high compared to how much work they can actually do because the gas runs out very quick.
Hey man! This video is brilliant! And i think it'd be great if you can continue this series and start making other fluorescent and phosphorescent compunds/complexes from scratch! 🙌🏼
Really nice and interesting video ! Actually letting zinc and sulfur will also make a fluorescent material. It also makes a spectacular flame but nasty fumes.
Do you know a bit of physics (or know anyone who does) I did a physics demonstration on my channel but need someone who knows to tell me if they can spot any big mistakes I might have missed. Thanks either way, keep up the great uploads!
Iirc copper (II) ions react with Iodide in redox that gives off copper (I) iodide and free iodine in 2:1 ratio. It would mean using more iodide salt but one might be able to just skip that reduction by sulfite. Though, it's probably just a question of if you want to deal with some sulfut dioxide smell or iodine vapours. Might be an insteresting way to make some iodine crystals though.
One of the best parts of your videos is listening your accent. I live in FL USA- the hottest place on the planet. I'm Tracy and it's excellent to meet you, Sir!
CuI is the only completely air-stable Cu(I)-halogenide. CuI2 doesn't exist. If CuI becomes brownish then because of remaining KI impurities oxidized to iodine. You should have prepared the acidified sulfite solution at last. It fastly loses a lot of its SO2 content and therefore part of its reducing potential on longer standing. I would recomment mixing stoichiometric amounts of CuSO4, KI, sodium thiosulfate and sulfuric acidic (15 % is sufficient) instead. This works very well, which can be recognized by a perfectly white precipitate of CuI (the brownish color of the mixture is an indication for a not completely reduced excess of iodine).
As a fluorescent mineral collector, that aside about not wanting to spend a fortune on a filtered UV light hit close to home lmao I will note that glass is a very good UV filter, which will mute some of any fluorescent response!
