When I was 12 years old my father use to bring me back chemicals from his metal plating factory and one of them I remember well was chromium trioxide. That was the last chemical he brought home for me as I spilled a bunch on the carpet and it melted into it lol. He was pissed about the carpet, not realizing them chemicals he was bringing home for me could have killed me. I remember I loved the chromium trioxide as it burned bright white in my smoke bomb compositions. I still to this day can't believe him bringing me this stuff home. I am still alive thank god.
Tommaso Petrella Yep, we had white phos in my high school chemistry lab! We had a new chem teacher who was just appalled and brought out that along with some red P, sodium, potassium, etc., in a box,telling us "these have no business in a high school chem lab", intending to dispose of them ASAP. But, he didn't have to - they disappeared that night. Today, that would probably constitute a federal breach of homeland security, or something. I'm glad that whoever took them must've been careful.
what an arrogant prick that teacher must have been ! I'd like kick his arse and educate him...any and all chems are acceptable in a chem high school lab...and those are standard stock items in all decent high school labs...and it is only his short sited attitude that makes these things troublesome...if he took the time to do demonstrations with these chems he could teach the whole class about the nature and correct procedures for using and handling these things...I cannot stress enough how appalling I find that kind of attitude...all it does is demonise things, teaches no respect and with holds essential experience to any students who want to take chemistry further...totally idiotic..
no way dude, he was just trying to keep us safe! I burned my finger badly on a hot day handling white phosphorus like it was wax. Nothing puts that out!

Hello, great experience, but what can you use CrO2Cl2 for? If I can suggest, try to get CrO2 .... or by thermal decay. Or a reaction with NaBr :) 2NaBr + CrO2Cl2 = 2NaCl CrO2 + Br2. I do not know if (in the moment it's just a theory) CrO2 is ferromagnetic below 386 K. If you know some methods of obtaining CrO2 in semi-laboratory conditions, please give.
Why didn't you have your hydrochloric acid bubble through basic solutions to neutralize it instead of letting it into your lab? Also, is there no way to prevent gasses from leaking out of your joints?
All the time spent watching your new 30 sec intro, however cool it is, will quickly add up...thereby depleting us of valuable learning time.

+JMAPScience Even fuming nitric acid is able to set your gloves on fire, there's no doubt this stuff is also capable of doing it. A small chemical burn is better than a completely burned hand with burned glove's peices in your skin. Furthermore, you're able to quickly wash drops of this liquid off, but I doubt you'll be able to take off a burning lab glove.
+DevilsVideos1 Actually most gloves would provide adequate protection against sulfuric acid. www.aps.anl.gov/Safety_and_Training/User_Safety/gloveselection.html Edit: You say "Even fuming nitric acid is able to set your gloves on fire" as if most acids set gloves on fire. To my knowledge, fuming nitric acid is the ONLY acid that will set neoprene/latex gloves on fire.
Not if you don't want a light wind to end your life... Flamethrowers are safer because the fuel is inert after its done burning. If you sprayed this stuff it would remain dangerous as long as it was airborne, regardless of how long it had been since it was dispenced.
No, it can't. You even said it yourself, it reacts "explosively". You don't want "explosively" for a flame thrower. You just want a fuel that you can set on fire as it leaves the flame thrower and a way to shoot it out of the end at a high speed with a lot of force. That's all.
Lordy. That stuff looks and sounds like Satan's own death-jizz. Cool synthesis and all, but as I don't see it showing up in any of your other videos, what on earth did you make it *for*?
+Rador Labs good question, water will react with CrO2Cl2 to form the chromic acid, so everything you collect from the distillation should be anhydrous.
Could have used glassware components to add the h2so4 without risking exposure to the fumes. Also should have added a granular solid scrubber to that last hosebarb and fluoropolymer grease to the joints of the apparatus. And black gloves of appropriate material (fluoroelastomer?) when grinding, not to mention a smaller quanity relative to mortar size.
always look at MSDS before doing an experement. I did an experement with potassium dichromate without looking at the MSDS for it and was lazily getting the dichromate solution on my hands. I got mad at myself for it
Why? Chromium trioxide is far more expensive than potassium dichromate. It would be wasteful to use that instead. And if you can get chromium trioxide, then you can certainly get potassium dichromate.
Do you ever worry about how you'll clean your lab after you're done with all these reactions? Also, how do you go about disposing of waste? Obviously you're not just going to wash the glassware after this and pour it down the drain...uh...right?
+Dennis Atwood He says to clean it with a lot of water and a reducing agent. Il will reduce the Cr+6 and dilute the acid. Then it would be relatively safe to discard.
Hazardous waste disposal is expensive and difficult. So acids, bases, oxidizers, and reducers are neutralized by mixing acids and bases (whether it is an acid or base you are disposing of, always add an acid to a base or a base to an acid) and mixing reducers with oxidizers (if it is an oxidizer, add a reducer, if it is a reducer add an oxidizer). With certain heavy metals (like copper and zinc) you can simply percipitate the metal or turn it into an insoluble salt and put it in a zip lock bag and put it in the trash, but Mercury or lead salts require special disposal. For toxins you can react it into a harmless thing like reacting cyanide into cyanate.
You figure that out before you do the reaction. If you don't know what you're going to do with the waste when you're done then you're doing it wrong. Even waste products can be useful though, so a lot of them are saved for other things.
those god damned equilibrium problems got me screwed up in school right now... i almost got it and it seems to be a base part of the understanding of reactions ?? idk im much more intrigued now
why would you want to heat it and distill it ? heating that chromyl chloride will surely decrease your yield....just let it settle out, it will separate because of it's high density, then if you REALLY think you have to , you can distill THAT, best to do it in a stream of dry air....but, actually , just blowing dry air through the product to remove the HCl gas is often all that is needed to get the product to a good level of purity, good enough that it can be stored without decomposition, cold, dark, sealed , no problem !.
@voitdive You are picking at words, but here Is a 5 second Google, wikipedia Chronic: CrVI can produce chromosomal aberrations and is a human carcinogen via inhalation.[8] Frequent exposure of the skin to chromyl chloride may result in ulceration.[7] It causes cancer, and it can cause cancer. Don't fuck around with chromium compounds unless you know what you are doin
@voitdive If it hydrolyzes it forms hexavalent chromium. Here is an excerpt hexavalent chromium from wikipedia. All hexavalent chromium compounds are toxic (due to their oxidizing power) as well as carcinogenic (IARC Group 1), especially if airborne and inhaled where they cause lung cancer. Also positive associations have been observed between exposure to chromium (VI) compounds and cancer of the nose and nasal sinuses.[5]

Hmm...could it be used as a solvent?
Not as a general solvent. Perhaps in a solvent less reaction where it was one of the reactants.
Yeah, this is what I was thinking of.
can i use ammonium dichromate in place of potassium dichromate?
Yes you can but ammonium dichromate is more useful and rare than potassium one
would that Corning high vacuum grease might've helped with the leaky joints?? Not wanting to be too much of a wise-ass.
Chromyl chloride attacks most grease. It's a pretty aggressive reagent.
