[@integral_chemistry]

Yeah the staining and choking fumes are definitely annoying.. especially the staining. Its (as far as I know) less dangerous than the rest of the halogens in its pure form, but that just means we typically take fewer precautions when handling it than bromine for example which makes the irritation definitely more noticeable.

Nice job! I think back in the day, I used iodine, red phosphorus and in the 20% chance the reactants weren't reacting, a drop or two of hydrogen peroxide to kick it off. Worked every time! From what I recall this reaction produced copious amounts of HI.

[@integral_chemistry]

Thank you! And hm I'm guessing it got the H from the peroxide through an intermediate reaction with the phosphorus. I've used iodine and red phosphorus instead of HI before in making methyl iodide which I assume follows a similar mechanism.

[@noimnotarobotcanubeleiveit7024]

Curbshot?

[@LabCoatz_Science]

I knew HI couldn't be made from sulfuric acid, but I had no idea it could be made from phosphoric acid (like you, I never had a use for HI, so I never checked lol). Very nice synth, I wonder if there's an easy way to remove the iodine color from the acid...maybe sulfur dioxide or sulfite followed by redistillation under reduced pressure or argon? Idk, it probably doesn't matter a whole lot, especially since you just converted it all to iodine anyway!

[@integral_chemistry]

Lol its funny, I was trying so hard to think of any feasible use for this as a demo for the video but it really just doesn't have any besides some excessively long organic synth. But yeah I think that general procedure would work to clear it up, reduced pressure might mess with the azeotrope though so argon would definitely be better. The only reliable way I've read about to perfectly clear HI is actually to bubble hydrogen sulfide through it and filter out the precipitated sulfur. H2S + I2 → 2 HI + S It would be crazy to see HI perfectly clear. Its a deep brown even in the wikipedia page.. I just HATE H2S lol

[@LabCoatz_Science]

@@integral_chemistry maybe a sulfide salt would work (either by reacting with the iodine directly or by forming H2S in situ)! Personally, I would've tried making some kind of organic iodide, since they're pretty good alkylating agents. Maybe try methyl iodide?

Another way to make very pure HI is to first make iodine from iodide then react the iodinr in water with H2S iin a N2 atmosphere in a flask with aggressive stirring. Sulfur coats the flask and very clean HI is created. It can be vacuum distilled yeilding a very pale yellow acid. It is best used immediately, but can be stored for months in a brown glass bottle under argon or nitrogen in a fridge. ❤

[@Pootycat8359]

2:32 That's often not the case. If it were, you couldn't make HNO3 or HCl with NaHSO4. H2SO4 is very strong, but HSO4(--1) is weak. When the salt & acid are mixed, there's an equilibrium between the starting acid & product acid. Even if it favors the left-hand direction, if the product is volatile, it distills off, in an ongoing process.

[@integral_chemistry]

100% agree. I did touch on that but I do think I should have emphasized the entropic favorability with gaseous/liquid acids being so much more favorable than sulfuric/phosphoric acid and their salts

That was fun to watch. I'm guessing you know this but to everyone else, if you just wanted iodine from KI, a bit of acid and/or peroxide will convert it to I. No need to make HI first (though that was a cool demo). Sulfuric will work, and has the added benefit of what was shown here (being able to make a puck of it) or you can do it with HCl and H2O2 (per "Sciencing" I googled): Pour 4 grams (g) of potassium iodide into a test tube. Add about 3 milliliters (ml) of distilled water to the test tube. Shake the test tube to dissolve the potassium iodide in the water. Add 3 ml of concentrated hydrochloric acid (HCl) to the test tube. Shake the test tube again to mix the hydrochloric acid into the solution. Obtain or prepare a solution of 97 percent water and 3 percent hydrogen peroxide. Add 20 ml of the hydrogen peroxide solution, and allow the solid iodine to settle to the bottom of the test tube.

I found a very interesting potential route to hydroiodic acid that could potentially be more attainable for amateurs. It can be formed as a byproduct of the hydrolysis of tin (IV) iodide, which itself is a very easy chemical to make, just reflux tin, iodine and chloroform. It forms very beautiful orange crystals. These decompose in water to yield hydroiodic acid. Just an idea I had that might work. Idk if the tin contamination is a problem, but I imagine you can distill it out.

[@mspalien]

I think the driving force for this reaction isn't that the thermodynamics drives the reaction to the right, but rather the volatility of HI as compared to the non-volatility of phosphoric acid. Its basically an application of Le Chateleir's Principle - distilling off the HI and removing it from the reaction drives the reaction to the right.

[@integral_chemistry]

You're definitely 100% correct on that! However, Le Chateleir's principle is just a statement of thermodynamics at the end of the day. It's driven by temp and state which are the two major variables that determine entropic favorability. I do like your explanation a lot more than mine though, especially for a more general audience. I definitely overcomplicated it for no reason lol

I'm not a chemist, I genuinely dont know the answer to this: could you use mineral oil for the melting step to suppress the vapor pressure? Or does the acid not dissolve a significant enough amount to make it worthwhile?

[@integral_chemistry]

Thats actually a good question, and I'm honestly not 100% sure. I know sulfuric acid would work better since it won't dissolve nearly as much iodine as mineral oil would, and the high density of the acid itself probably helps it suppress the vapor pressure more efficiently. Also sulfuric acid pulled water out of the iodine which mineral oil wouldn't be able to do. I think mineral oil would probably be possible but as you said the lower efficiency compared to acid might make it not worth it.. especially considering the insane cost of iodine (stuff is very expensive)

Not sure what the laws are for those of you overseas from Australia or interstate from South Australia but here in South Australia hydroiodic acid is classified as a section 17B illicit drug precursor chemical, however that does not mean that it's outright illegal to be in possession of it, buy it or use it it simply means that some legal restrictions apply to the possession, sale and use of it such as a good reason for possesing it and a written EUD statement declaring that it will only be used for legal purposes is required to be submitted to South Australia Police but it's not outright banned or illegal.

[@Franklin-jj4jz]

I would think that very pure HI could be produced by circulating dilute HCl through a column of ion exchange resin that has been activated with a solution of sodium or potassium iodide. The resin would swap its iodide ions for the chloride ions in the HCl, progressively increasing the HI concentration in the solution with each pass. When equilibrium is reached, simply recharge the resin and continue for higher concentration of HI.

[@ashe1.070]

Have you ever considered synthesizing nitroethane? There’s an interesting method that involves the oxidation of pyruvic oxime with sodium perborate in acetic acid at about 50-60 C. The resulting α-nitropropanoic acid should undergo decarboxylation readily giving nitroethane (in theory at least). Someone suggested this on Sciencemadness awhile ago, but I’ve never heard of someone actually trying it. I’ve always wondered if it would work, but I haven’t had a chance to do any experiments with it yet. So, it’d be really neat to see someone trying this reaction out, and posting the results! Also, there’s a paper on this type of reaction that was published in Synlett in 1992. It’s titled “Convenient Oxidation of Oximes to Nitro Compounds with Sodium Perborate in Glacial Acetic Acid.”

The process is generally the same, but hydroflouric acid has two unique properties that make it particularly hazardous. #1: Hydroflouric acid dissolves glass (and it's actually one of the very few chemicals that can). Therefore to distill HF this setup would have to be recreated with all copper, iron, or ideally Teflon rather than glass. #2: hydroflouric acid is an extremely lethal poison through both skin contact and inhalation. There is an antidote (calcium gluconate) but the toxicity and inability to be contained within glass is a scary combo.
