I Dissolved My Tooth in SELENIC Piranha!

I upgraded the typical piranha solution by replacing sulfuric acid with selenic acid! H2SeO4 + H2O2 60% and compared their properties!

"I know this video was not very spectacular" Maybe, but most interesting for all us chemists out there. Trying out something and informing about your conclusions without much ado - I liked that. I happen to love anorganic chemistry, and you deliver like no one else!

[@Lordhitchy]

I'm not even a chemist and I find this extremely interesting and informative (even if I don't fully understand most of the chemicals)

[@spiderdude2099]

Man, I didn’t even consider you could make selenic piranha. Very cool :3

[@Theriodontia4945]

I considered the idea of selenic piranha myself, but thought that the idea would be too niche (and selenic acid too expensive) to see a video about on KZbin.

[@SodiumInteresting]

I made selenic acid and copper tetraamine copper (II) selenate on my channel a while back, it's just like the sulfate only selenium salts tend to want to be selenium again more than sulfur does anyway. That's what makes selenic acid so tricky to make

[@pezboy715]

You may describe this video as “not very spectacular”, but I disagree. Where else do true chemistry nerds like us get to observe such exotic reagents and reactions? Please never change and don’t sell yourself short. Sincerely, A Proud Patron 😊

[@paulanizan6159]

I actually enjoyed this video, having studied chemistry when I was much younger than today.

[@nuneke0]

Looks like your tooth had a "head start" dissolving... 😁

[@alexhatfield2987]

The tooth was interesting…..now we know a Selenic Acid Piranha solution is the go-to method for dissolving bodies.

[@herrbrahms]

Too expensive to dissolve the whole body. Use KOH for that, and only bother with piranha solutions later if you want to get rid of *everything.*

I know gold is typically very unreactive and only dissolves in a limited number of things, but is there anything that can actually dissolve iridium?

[@SodiumInteresting]

Aquaregias like HCl/HNO3 or HCl/HClO3

[@petevenuti7355]

Is there any metal that won't dissolve in hydrochloric + perchloric?​@@SodiumInteresting

[@SodiumInteresting]

@@petevenuti7355 that's chloric not perchloric but yeah don't know, I used sodium chlorate in hcl to dissolve gold

[@grebulocities8225]

Aqua regia will not dissolve iridium, but @PoorMansChemist reported that it will dissolve in a 50/50 mixture of molten KNO3 and KOH. Molten cyanide salts will also dissolve it, and it can also be attacked by hot fluorine or chlorine. I don't know of a way to put it into aqueous solution directly though.

[@SodiumInteresting]

@@grebulocities8225 Thanks I have not worked with iridium, now I want to

[@ianbd77]

Brilliant, thanks ❤🎉

[@jozefnovak7750]

Super! Thank you very much!

[@skyethebi]

I’m wondering if the selenic acid may have just oxidized some of the peroxide to oxygen and that caused it to be less effective. There’s also the possibility that selenic acid is a much weaker dehydrating agent than sulfuric acid since the dehydrating ability is what really drives the reaction with many organics.

[@DerDrako]

Great video and thank you for your sacrifice. ;)

[@Auroral_Anomaly]

Nah, the second I saw the title I had an aneurysm.😭

[@KeepAnimeDegenerate]

Another interesting reation I'm curious about is the TCCA and HCl reaction. What if one were to use HBr instead? Instead of generating chlorine, would you get bromine monochloride or just a mixture of two halogens chlorine and bromine?

[@jasonmorgan661]

Could you show us some cool etching chems for glass and metals from your perspective ?

[@patrickstar7693]

can you also create a piranha solution with Fluoro sufonic acid?

[@jonathanfalvo2414]

I started thinking about the similarities between selenium and sulfur. The idea came to me that selenic acid probably exists and is most likely as strong stronger than sulfuric acid. Not only did I find it, but I found it made into a piranha solution👍👍👍👍 very satisfied

[@donkeypunch236]

Great video.

[@marcopolo8584]

You can increase the concentration of your hydrogen peroxide by putting it under vacuum in a chamber with drying agents. However it's a very time consuming and wasteful process, and Ex&F Tom noted that it often seemed to decrease the effectiveness of the solution, he hypothesized this is due to the lack of water making aqueous reactions occur more slowly.

[@lmost]

Very, very cool!

[@fatman9644]

Can you demonstrate the reaction of H2O2 with LiAlH4

[@user-hs2sq1bc9o]

Разве реакция Не пойдет без добавления Перекиси ?

[@ZoonCrypticon]

Very interesting video, thank you ! Now, what compound has formed after the selenic piranha solution dissolved the gold ? Gold-selenate Au2(SeO3)2(SeO4) ? Can it be crystallized ?

[@afanas-artur]

Au2(SeO4)3. It can be crystallized, but it will be not very easy to do. HNO3+HCl is more recommended to desolve Gold.

[@ferminenriquezamorapineda2832]

Can ozone oxidize selenium dioxide or sulfur dioxide?

[@beardedchimp]

Your tooth looks like an acid had already had a try. Thinking about it, how does plaque (or other decay mechanisms) break down teeth? I'd guess bacteria produce acid(s) during respiration, is the dissolved enamel actually used at all?

[@anthonyodea2251]

It is possible that the tooth cracked when it was being removed, as opposed to such a significant amount being decayed by bacteria.

[@herrbrahms]

Oral bacteria metabolize sugars and produce lactic acid as a waste product. This wouldn't be so much of a problem since saliva is basic, except the plaque biofilm keeps the acid in contact with the tooth and away from saliva in the absence of frequent brushing and flossing. Fluoride is added to toothpaste because it replaces the weak -OH groups in tooth enamel hydroxyapatite, making fluoroapatite instead.

[@beardedchimp]

@@herrbrahms that is fascinating, thank you for enlightening me. My nephew has cystic fibrosis, researching it several years ago gave me terrified respect for biofilms. In his case they prevent antibiotics from killing pseudomonas, if an infection is detected before the biofilm has matured it can be treated. With CF, fighting a fully colonised biofilm covered lung infection is nearly impossible. I'm wondering what's the function of plaque's biofilm. Obviously it can tolerate basic saliva already, does it act as a lubricant preventing abrasion during eating from scraping the underlying bacteria? I did some googling prior, but honestly succinct comments like yours are far more informative. > it replaces the weak -OH groups in tooth enamel hydroxyapatite, making fluoroapatite instead. So you're saying fluorapatite is in on the global mind control conspiracy? :P

[@herrbrahms]

@@beardedchimp The function of the plaque biofilm is less a lubricant and more an adhesive. It's produced mutualistically to benefit the entire colony. It seems clear this evolved through natural selection; after all, an unadhered bacterium will eventually wash down the gullet of the host and find certain death in the stomach. The fact that lactic acid produces cavities is just a bonus from their perspective, since it creates more nooks and crannies to colonize. The plaque is safer out of the weather, so to speak. I don't know if it was clear earlier, but the hydroxyl groups are susceptible to acid attack while the fluorides are not. But microorganism adhesion to flat surfaces has evolved many times. Consider how lichen can find purchase on smooth exposed granite in tundra environments. Fast forward this process over geological time, and it's one of the ways that rock becomes soil. Don't let your teeth weather away to soil. And it's very unfortunate that we can't just brush our lungs the way we can our teeth.

[@Bartixxl]

Could you make Basic piranha?

[@CTCAC2000]

bottoms up!

[@user-dc8em3ou2z]

Can you do one with Hydroiodic acid? I've never seen this acid being used on any channels on KZbin yet, and I read that HI is way more powerful than HCL or all of the Halogen based acids! Thanks

[@stefangadshijew1682]

HI is only more "powerful" as in more acidic in other solvents then water, and probably as a gas. In water, all of the hydrohalogenic acids except HF are completely disassociated. Also, HI tends to be a reducing agent, which might open some chemistry you can't do with the other acids, but makes it more messy and less useful if all you need is a strong acid.

[@NetRolller3D]

[@StuffandThings_]

When you dissolved your tooth, it made me think of something. Teeth and bones contain a good record of lead intake, so could you extract lead from your teeth to determine your lead intake?

It seems that if you want to make selenic acid yourself it would be easier to use the H2O2 oxidation of SeO2, here is the DOI of a paper detailing it: 10.1021/ja01292a501 Also, the gold selenate can be crystalised by addition of water since it is very insoluble.
