And by the way: will it work with Lugol's Iodine? Lugol's does allways have some KI in it because of this equilibrium: I2 + I− ⇌ I3− so i thought the reaction would use the KI in the solution and then more would be formed due to Le Chatelier's principle.
@cassiavc I would ask the same. Is there any formation of hydriodic acid? If I am interested on the hydriodic acid, can I filtrate it? How strong is HI compared to HCl? HI sounds to be a good acid to mess around with xD
I did this but instead of using solid potassium iodide, i bought it in solution, but it won't work. all i get at the end is see-through brown liquid what should i do?
@sciencenurd2 the concentration matters because the number of molecules of hcl must equal the number of molecules of the iodine salt for the reaction to be completed. However, if the concentration is different, you can use stoichiometry, a part of chemistry, to find how much volume you need to match the amount of iodide you put in.
@sciencenurd2 12M is highly concentrated, so it should work, but be very careful when handling it. The goal here is to have the same # of particles of HCl as of the iodide, or maybe a bit more to ensure that the reaction finishes, so if you have one liter of HCl, you will have 12 moles, a unit measuring the # of particles, of HCl. You should get the same # of moles of the potassium or sodium iodide, or maybe a bit less. The atomic weight of an element on the
@sciencenurd2 periodic table is actually a measure of grams per mole. Add the weights of the elements you use (potassium or sodium and iodine) together to find the grams per mole of the compound, then divide the grams of iodide you want to use by the grams per mole of the iodide molecule to find the number of moles of iodide you wish to use. Then, use a fraction of a liter of the HCl which counters the moles of iodide; 0.1 liters gives 1.2 moles. Be very careful of the HCl.
@TheMichaelnoob Chlorine ion replaces iodine from sodium iodide, making hydrogen iodide and leaving sodium chloride behind. I'm not sure but I think NaCl is not soluble in hydriodic acid (hydrogen iodide in water), and thats why it precipitates. Then hydrogen peroxide oxidizes HI back to elemental iodine, and H2O2 is reduced to water. Chlorine gas is generated as a byproduct the same way iodine is produced.
@TheMichaelnoob H2O2 is a strong oxidising agent and hence it oxidises a little chloride to chlorine; not much though as chlorine itself is also a powerful oxidiser.
I preformed this experiment and i had a problem with drying the iodine before purifying it as i felt that just leaving it out to dry made me lose a lot of product. My cooling bottle on top collected some condensed water which lead to my iodine now being contaminated with just a little bit of water. Any ideas on how to remove the water without losing to much of my product?
Thanks! And youre videos are a great source of inspiration.
So,if you mix this (let's say) Potassium iodide solution with hydrochloric acid and hydrogen peroxide,you get iodine,and this "liquid" is actually a "solution" of potassium chloride in water ?? 2KI + 2HCl + H2O2 --> 2KCl + H2O + I2 Is there any way to extract KCl from that mixture ??? btw,nice vid,man :D
But most of the I2 crystallized on the sides of the beaker, not on the flask. And apart from some needle crystals it was hard to get it off. In the end it was pretty hard to clean the beaker. Some tips: Sodium thiosulfate solution dissolves iodine and can remove stains. Don't use metal spoons or scoops for handling or scraping iodine---they get attacked and corroded almost immediately. I don't think you need ice---cool water would work, and the ice condenses water from the air, a nuisance.
@annaandherdad nice pentuple post bro, I foresee a spam-flagging arising because someone won't actually read your comments enough to realize it isn't just lame copypasta.
@annaandherdad Thanks anna's dad. You should take some photos next science experiment and post them up at science madness so there's a more permanent record. One thing that is better about this HCl method is that using only sulphuric may mean hydrogen sulphide gas is given off. H2S is the second leading cause of industrial deaths, 1 behind fire. It also has a truly immense stench to it! When I've been doing things with it, people could smell it outside the house it was that bad.
Well I'm dumb. Nurdrage already explained in the video that the crystalline stuff you get when you add HCl is NaCl (KCl in my case), and at the beginning of the comments below he also explained what causes the yellow color. As for the recrystallization, it wasn't nearly as easy as I thought it would be. We tried to recrystallize about 10gr I2, heating it in a 250ml beaker with a round flask full of ice on top. I would use a smaller beaker if I did it again. (continued)
I realize we shouldn't expect Cl gas until we added the H2O2, but didn't get much then. One more thing---if you do this, wear gloves! The I2 stains everything, skin, clothes, gloves etc.
Then added 100ml 3% H2O2, got iodine precipitate immediately. It was easy to wash with water and gravity filter. When dry we will recrystallize as Nurdrage does and save the I2 in a vial. I was worried about dangerous fumes (HCl, Cl2, I2), but the worst was the usual from HCl. Nurdrage, if you read this, my daughter watches you every weekend. We love your videos, and have learned a lot. Thanks!
We did this experiment. It worked very well. We used 13gr KI + 10ml water in a 150ml flask. A little water dissolves a lot of KI, and it gets cold! My daughter found that very interesting! Then we added 10ml conc HCl. It became slightly yellow and deposited crystals all over the sides of the flask when we swirled it. I suspect the crystals were KCl (less soluble than KI?) Don't know what the yellow was. We were prepared for Cl gas but didn't get much if any. (Continued)
@h0meIandsecurity myst32YT has a video showing how to make Iodine from povidone-iodine. Look him up on here and check it out. He has other cool videos too.
vaporization crystallization? i'm unfamiliar with that technique even as a college chemistry major. can someone explain how the technique is performed?
@h0meIandsecurity percent is the amount by mass, so in 100g of 19% HCl there is 19g of HCl, from there you can calculate the moles, you don't need to calculate concentration for this particular experiment, since its more about the moles.
Okay...for some reason this epic failed...? Explanation please? I precisely followed each direction...how concentrated does the HCl have to be? I think that is what went wrong
Can you make a video on how to get iodine from either tincture of iodine or povidone iodine? I think this is the closest thing you can get at a drugstore.
The magnesium powder test seems to only work when the iodine is damp (I tested some reagent grade I2 from Aldrich) or if a drop of water is added to the mixture of Mg powder and I2 crystals. Was your Iodine still moist when it was tested? What mesh of Mg powder did you use? .... BTW: The test seems to also work with Zn powder (with a somewhat less dramatic result), but again, only when moistened.
Liquid elemental bromine (Br2) can similarly be isolated by the action of conc. H2SO4 on NaBr or KBr followed by distillation of the Br2. If aqueous H2O2 is added in the right proportions to a mixture of NaBr or KBr and H2SO4 then a layer of liquid Br2 will be formed, since nonpolar Br2 is (mostly) immiscible with the now aqueous solution. Another option is the action of H2O2 on a solution of NaBr or KBr in HCl followed by distillation.
NaBr is readily available at your local swimming pool store as a "bromide reserve" starter for hot-tubs that are to be disinfected by bromine compounds instead of chlorine compounds. However, when distilling make sure to use only glass equipment as bromine will destroy any plastic or metal used in the distillation setup.
@theyellowdartALT Also, bromine is extremely toxic and corrosive as well as volatile so be sure not to breathe the fumes or get any on you. Do this in a hood or outside while using respirators intended for corrosive gases from your local hardware store.
@lanschr0 I would assume salt won't participate in such a reaction, so maybe you can use the iodized salt. You would probably need LOTS of it, however.
your probably the coolest person on youtube that does chemistry haha, but i have a favor to ask. could you do a video on how to make pure crystals? like salt or sugar crystals. ones that are clear would be amazing
Have you read about how they get iodine from sea water? It is insane how they are able to concentrate it from such low levels. They should show it on "How it's made".
In my stupidity I accidentally got my iodide to come in to trace amounts of copper sulfate, it is now yellowed. Is this contaminated iodide suitable for this experiment
The most interesting part of iodine is that it can produce alkanes out of almost every primary alcohol, if reducted with phosphorous. I have read lithium may do the same, but i dont know if it would form an alkoxide.
no because 1. copper is much lower on the reactivity series than sodium and 2. even if the copper was more reactive, because of it's +2 oxidation state, it would generate copper (II) iodide not copper (I) iodide.
I wasn't talking about sodium iodide I was talking about potassium iodide.
Even though potassium is much more electron positive (reactive) than copper it still switches. Like when Na2CO3 and CuSO4 are mixed it makes Na2SO4 and CuCO3 even though sodium is much more reactive than copper. Also copper(II)iodide is made which decomposes to copper(I)iodide and iodine.
Okay so i a solution of potassium permanganate an preparared d potassium iodide. Then added it to hydrogen peroxide. the result was odd.... I smell a little chlorine and the solution has been bubbling for ten minutes + someone here said it could make iodine. So i decided to find out. I placed it outside and put a bucket over it to keep animals out. It looked like manganese oxide and small amounts of iodine are being produced.
Hey Nurdrage, I did everything you said and i purified it perfectly. Just one question, when i purified it, there was a residue of contaminants on the bottom of the beaker. What is this made of?
I was talking to the dean of the science department at my school about this. Apparently iodine is useful in making meth, so the DEA has toughened up the regulations to get it. Too bad you can make it with household stuff :D. Yay for idiotic bans!! :D
@EL71994, No, H2O2 is needed to oxidise iodide ions to iodine. You could also use potassium permanganate or a chorate in its place, but these aren't very safe to use, so I'd avoid them.
No, you can't use potassium permanganate (well, unless in base, but iodine formed will disproportionate) or chlorate because they will oxidize iodide to iodate instead of iodine.
Oh, and do you have any recommended experiments that I can ask my teacher to do in science-class? I'm only in 9th grade, so can't do something really advanced :P
@NurdRage True. However, just to provide you with information, normal-sized stars (like our sun) cannot make Iodine. They cannot make any element with a proton number higher than that of Iron. The reason for that is to fuse elements lighter than iron evolves energy, however to fuse elements like iron or higher takes energy. Therefore, Iron is the end product of normal fusion in stars. However, Iodine and the heavier elements (compared to iron) are made only during a supernova explosion.
No way! It is totally impossible to make iodine via stellar fusion (though quite possible in a nuclear reactor). Even the biggest stars produce little past iron (element 26). This makes it virtually impossible to produce something all the way at iodine (element 53) until a star goes nova (or supernova).
@HLiNaKRbCsFrUun correct me if im wrong, but firstly, they can even fuse hydrogen in a nuclear reactor so how do u expect them to make iodine, and secondly, if stars don't make it then where does it come from? they have to make it
I didn't say that it wasn't made in stars. It isn't made in stars until the star goes nova or supernova, at which point it makes small amounts (that is "natural iodine"). And of course they can make iodine in a nuclear reactor, I never said that they couldn't.
instead of hydrogen peroxide you can use laundry bleach and for the hydrolic acid you can use muriatic acid for the sodium iodide you can use iodine tincture
Do you know if i can produce Iodic acid by Oxidizing I2 with Chlorine in an aqueous solution? Potassium Iodate is an good pyrotechnical oxidizer as well as a anti Radiation drug, it's produced from Iodic acid.
Its not that easy. you'll probably end up forming a whole lot of iodine trichloride in the reaction or not getting a reaction at all unless you have the conditions perfect. you're better off buying potassium iodate or using a different oxidizer.
YAY my KI came today and i just did this. freakin awesome. but whats the yellow stuff formed after the HCl is added? also what's the brown stuff dissolved in the water after the peroxide is added?
Great Video! One question though. You check for reactivity using magnesium. I remember seeing a video where bromine reacts with aluminum in a similar manner. Is Aluminum not reactive enough to react with iodine in the same way? Is it too slow of a reaction?
But the good thing about this method is that it's very forgiving, you can be off by quite a bit and still get product albeit at reduced yield. So go for it without too much worry,
And by the way: will it work with Lugol's Iodine? Lugol's does allways have some KI in it because of this equilibrium: I2 + I− ⇌ I3− so i thought the reaction would use the KI in the solution and then more would be formed due to Le Chatelier's principle.

Can I make iodine this way?
4KI+2Cu(II)SO4=2K2SO4+2Cu(I)I+I2
AHW214 2 years ago
no because 1. copper is much lower on the reactivity series than sodium and 2. even if the copper was more reactive, because of it's +2 oxidation state, it would generate copper (II) iodide not copper (I) iodide.

@japanesepoptart
I wasn't talking about sodium iodide I was talking about potassium iodide.
Even though potassium is much more electron positive (reactive) than copper it still switches. Like when Na2CO3 and CuSO4 are mixed it makes Na2SO4 and CuCO3 even though sodium is much more reactive than copper. Also copper(II)iodide is made which decomposes to copper(I)iodide and iodine.

how about adding nitric acid to copper iodide?
adriiPortillo 1 year ago
@adriiPortillo
You should ask Nurd Rage about that.
Even if I'm wrong, which I probably am, this is the equation I made for copper iodide
and nitric acid: 4HNO3+2Cu(I)I= I2+2Cu(NO3)2+2H2
If I'm wrong, could somebody please correct me. Thanks.
AHW214 1 year ago
@AHW214 Yep, i would add, following this video's main idea:
I2 + H2 ---> 2HI wich would occur at you equation. we add hydrogen peroxide and:
2HI + H2O2 -- > 2H2O + I2
adriiPortillo 1 year ago
when i do it i usually eyeball the quantities. this [for some reason] does not generate chlorine gas. usually the iodine is slightly pasty.

Okay so i a solution of potassium permanganate an preparared d potassium iodide. Then added it to hydrogen peroxide. the result was odd.... I smell a little chlorine and the solution has been bubbling for ten minutes + someone here said it could make iodine. So i decided to find out. I placed it outside and put a bucket over it to keep animals out. It looked like manganese oxide and small amounts of iodine are being produced.

Hey Nurdrage, I did everything you said and i purified it perfectly. Just one question, when i purified it, there was a residue of contaminants on the bottom of the beaker. What is this made of?

I was talking to the dean of the science department at my school about this. Apparently iodine is useful in making meth, so the DEA has toughened up the regulations to get it. Too bad you can make it with household stuff :D. Yay for idiotic bans!! :D

EL71994 2 years ago
is H2O2 a catalyst in the reaction?
EL71994 2 years ago
@EL71994, No, H2O2 is needed to oxidise iodide ions to iodine. You could also use potassium permanganate or a chorate in its place, but these aren't very safe to use, so I'd avoid them.
SonOfFurzehatt 2 years ago
No, you can't use potassium permanganate (well, unless in base, but iodine formed will disproportionate) or chlorate because they will oxidize iodide to iodate instead of iodine.
And yes they aren't safe as well.

Technically, you're not 'making' iodine, you're chemically removing it from a more readily avaliable compound. Nice vid though!

@NurdRage you are both wrong! because if you wish to create iodine from scratch, you must first invent the universe...

thekillerhjkhjk 1 year ago
@NurdRage True. However, just to provide you with information, normal-sized stars (like our sun) cannot make Iodine. They cannot make any element with a proton number higher than that of Iron. The reason for that is to fuse elements lighter than iron evolves energy, however to fuse elements like iron or higher takes energy. Therefore, Iron is the end product of normal fusion in stars. However, Iodine and the heavier elements (compared to iron) are made only during a supernova explosion.
ScienceTry 1 year ago
@NurdRage
No way! It is totally impossible to make iodine via stellar fusion (though quite possible in a nuclear reactor). Even the biggest stars produce little past iron (element 26). This makes it virtually impossible to produce something all the way at iodine (element 53) until a star goes nova (or supernova).
HLiNaKRbCsFrUun 7 months ago
@HLiNaKRbCsFrUun correct me if im wrong, but firstly, they can even fuse hydrogen in a nuclear reactor so how do u expect them to make iodine, and secondly, if stars don't make it then where does it come from? they have to make it
Lachieh923 6 months ago
@Lachieh923
I didn't say that it wasn't made in stars. It isn't made in stars until the star goes nova or supernova, at which point it makes small amounts (that is "natural iodine"). And of course they can make iodine in a nuclear reactor, I never said that they couldn't.

Do you know if i can produce Iodic acid by Oxidizing I2 with Chlorine in an aqueous solution? Potassium Iodate is an good pyrotechnical oxidizer as well as a anti Radiation drug, it's produced from Iodic acid.

Its not that easy. you'll probably end up forming a whole lot of iodine trichloride in the reaction or not getting a reaction at all unless you have the conditions perfect. you're better off buying potassium iodate or using a different oxidizer.

YAY my KI came today and i just did this. freakin awesome. but whats the yellow stuff formed after the HCl is added? also what's the brown stuff dissolved in the water after the peroxide is added?
rofl082193 2 years ago
Hydroiodic acid forms after the HCl is added and turns yellow as it's slowly oxidized by air. The brown stuff is just triodide ions.

Great Video! One question though. You check for reactivity using magnesium. I remember seeing a video where bromine reacts with aluminum in a similar manner. Is Aluminum not reactive enough to react with iodine in the same way? Is it too slow of a reaction?

not reactive enough.

Should i still use equal amounts of hydrochloric acid if my acid is 20% concentration? or should i use a bit more acid?
hexamethyltetramine 2 years ago
use twice as much acid.
But the good thing about this method is that it's very forgiving, you can be off by quite a bit and still get product albeit at reduced yield. So go for it without too much worry,

I see. What was the concentration used in the video? 30%?
