  • will with help me from Japan nuclear disaster?

  • nurdrage you are awesome!

  • where can you buy corrosive acids,as an individual not business or school???

    sulfuric acid mainly

  • @elflordbob1 Google is your friend. There is plenty of info on acquiring sulfuric acid. There are also youtube videos on the subject.

  • @purplemutantas

    thanx i found a website ...but my mommy wont let me buy it :(

    lol jk

  • 2:28 then look at the Backround

  • O.o fuck science!

  • Wow, we have the same watch. I feel realized.

  • Very good chanel and videos. My question is as follows: how do you dispatch all the chemical waste produced by the experiments?

  • @JorgeBM2204 Since he's at a lab I'm sure they have the necessary ways of disposing it all, but I've been wondering the same thing for at home, small scale things.

    I assume you could do a search for a place near you that handles chemical waste. At least, that's what I'm about to do.

  • @mcgoo721 and JorgeBM2204

    if your wastes do not contain heavy metals like lead, or especially mercury, or any organic compounds you can just flush them down your drain pipe, but there might be different regulations on disposing wastes in your country/state

  • Notice that the vapor at the end actually STAINED the advertisement paper in the back orange! I will do this.

  • smoke grenade!!!!!!!

  • I made iodine today with 40% sulfuric acid and potassium iodide. It was not so messy ;-)

  • I have no idea wt hell he is doing... and why he's changing his voice.

  • fuck you DEA

  • reminds me of mewtwo

  • is the fume at the last reaction, poisonous in any way?

  • @barrowscasper12 Yes, iodine vapours are quite poisonous.

  • that was amazing you guys are really smart

  • Alchemist..!

  • Is it possible to test the reactivity with magnesium ribbons?

  • cool iodine into iodine :O 0:42

  • Why do you need to pour the iodine slurry into the same ice water bath?

  • At first it looked like bromine

  • only on pure iodine on adding magnesium it reacts,coz i have tried it bt i didnt got the result of last test ?

  • @anandh1994 sometimes a drop of water is needed to get the reaction going.

  • @NurdRage well thabks alot because of this video there's jizz on my laptop's screen. great vids, i watch everyday;)

  • @NurdRage where Can i get magnesium powder? and can i somehow tale the sulfur and oxygen atoms out onf epsom salt to get the magnesium? Because in the uk it is impossible to get magnesium powder!!!

  • @mcwario13 You could try heating magnesium oxide with carbon in a crucible or just buy magnesium ribbon

  • @NurdRage :O first time ever seeing your comment

  • @anandh1994 I use a Magnesium ribbon, so it takes a while. Try making an Iodine solution and wetting the ribbon with it. This accelerates the reaction

  • Where/how can i get/buy/make magnesium powder other than grinding it

  • Could you make bromine with potassium bromide?

  • i love the sublimation of iodine

    your wall is still green after that ???? strange :D

  • OMG hydrogen sulfide! ya i'm gonna go the HCl/H2O2 method...

  • did the iodine just turn liquid?!

  • Gasses prodused arent toxic they are radiactive(iodine 131)

  • hopefully someone knows an answer for me i make copper sulfate and zinc sulfate by making a weak solution of sulfuric acid by mixing sodium bisulfate into distilled water until no more disolves after these experiments i wanted stronger sulfuric acid so i made my sodium bisulfate and boiled it down and set it aside well i wanted it stronger so i boiled way down to almost no liquid left and i let it cool when i checked back on it it had crystallized into really sharp crystals what are the crystals

  • @HUsoldier171 "what are the crystals"

    Sodium Bisulphate. Boiling it down won't help when making it this way. See if you can find battery acid (32% sulphuric). Dilute it down by three & you'll get 1 M bench acid & three times as much. Boil it until it's fuming, you'll have concentrated acid, but about a third of what you started with.

    Sulphuric boils at 300C+. The fumes pouring off are extremely acidic. If the hot acid spits at you, it will burn immediately on contact <- experience not hearsay

  • Battery acid is available from car garages in refill bottles. It is a good source of clean acid, as it has to be clean to function well in the battery, so nothing is added to it. Because it is also around 32%, it does not react so readily with it's container, contaminating it's self; as concentrated acid does.

    I would not recommend concentrating the acid unless you actually need to. Concentrated acid does not always function better & boiling it is extremely dangerous.

  • @lexichronicle2 that doesnt tell me what the freakin crystals are i dont care about concentrated sulfuric any more

  • @HUsoldier171 Sodium Bisulphate. The first thing I said in the reply.

  • @lexichronicle2 you didnt say anything about that in the reply

  • i don´t know what thi s was but it looked pretty coool :D

  • @drdrdr13 Iodine is an element that purifies water, similar like chlorine tablets. However, if you buy iodine directly you have to fill out certain forms and have to be on watch by the DEA ( Drug Enforcement Administration ). Of course most people do not want this, so they follow this procedure to bypass the troubles. Mainly they use the hydrochloric acid and hydrogen peroxide procedure because the chemicals are more available ( meaning to individuals ), but is more costly.

  • "Iodine is an element that purifies water"

    It tastes nice in water as well! :P

    I've left glasses of water out overnight while I've been using iodine. Some of it ends up in the air, and then in the water. Even the minute amounts of it passing over are enough to taste the next day. I also love the smell.

    Absolutely BRILLIANT surgical wash. Does very little to humans, bar stain them brown for a while, and annihilates the bacteria. Infection rates would be much, much higher without iodine.

  • could you think of way to extract iodine from green walnut shells?

    thanks for the videos !!!

  • @barbalote2 Actually, it is much more easier just to obtain the chemicals as seen here in this video. Also because they are cheap and can be purchased very easily.

  • Don't have any potassium iodide but i do have some sodium iodide. Sodium iodide should work right?

  • Nice and all, but could you pleeeeaase tell me how to extract iodine from iodized salt?

  • whered he get the acid :o

  • I love when he spins things weeeeeeee!

  • @h0meIandsecurity u r retarded! potasium iodide is expensive but the answer is right there in the name, KI. so 50%. with loss ya still get close to half of what ya put in, in moles. do the math and there ya go.

  • awesome video, and nice watch!

  • You could demonstrate how to get iodine from seaweed, i'd like to try it out

  • are u a wizard?

  • LOL in 8th grade my science teacher was giving demos during a period where we had these government officials come to our school to evaluate the school for awards and recognition for being a good school. Anyways. my teacher at the time MRS M(rip) was playing with iodine and she spilled it all over her hands in from of these people. her hands were died purple for about 4 days. We also lit magnesium in class, and put sodium and lithium in water. AHH THE VIOLENCE.

  • Here is my question: for those of us attempting to do this on an "open cabinet" basis, could a household Beta-dyne solution be used in place of the metallic iodide crystals?

  • what can iodine be use in, other then antisemptic and radiation absorver?

  • excellent!!

  • Comment removed

  • Oh, crap. I thought I had wiped out my seemingly less than imperative first post; not posted it.

  • Dr. L,

    I recently tried this out in my home lab. I just want to add something from personal experience to aid the other experimenters in the resublimation.

    Don't add the ice slurry to the RB flask until right about when the iodine begins to sublimate, then immediately place it over the beaker. Letting the slurry sit in the flask generates condensation which interferes with the crystallization of the iodine; it drips down into the beaker. I had to dry my iodine out again before proceeding.

  • Dr. L,

    I recently tried this out in my home lab using hardware store sulfuric acid (Liquid Lightning Drain Opener) instead of wasting good clean acid. I'm not sure if this occurs when lab-grade sulfuric acid is used, but when the acid comes into contact with the KI solution, a brownish haze is formed, and the smell (sulfur, like rotten eggs) is enough to clear an entire skyscraper. I just wanted to warn your other experimenters against performing this in an enclosed area. I did it outside.

  • @Xveckthorn The smell was most likely from the reaction between hydrogen iodide formed and sulfuric acid, it produces sulfur dioxide as a byproduct.

  • @FULANINHOM  no, because iodine is an element, elements cannot be reduced by chemical processes.

  • This experiment makes me want to try it with normal grocery store iodized salt with sodium iodide. I realize that it's a mixture of salt and sodium iodide, but it'd be cool to see about what the percent of the mixture is sodium iodide.

  • @benrr101 You would be disapointed. I think nutrition salt contains probably a few ten milligrams iodide in one kilogram NaCl.

  • I just love how his sign gets stained that burnt orange :D

  • Is there any way to do the opposite process, turning iodine into sulfuric acid??

    Thank you.

  • @FULANINHOM dont hav acces to sulfuric acid? same i cant get any i need a company i was gonna say nurdrage, using sulfur and potassium nitrate or something can you burn the sulfur making sulphur dioxide using potassium nitrate as an oxidiser then condense it with water to make sulfuric acid?

  • idk whats going on but it sure looks fun........to look at

  • looks like coke

  • Dr. N. Butyl Lihium

  • Is that alright K5? Alright. Nice one... alright....

    mmmmmkay

  • The process the Nurd uses at the end to purify his iodINE is sublimation. Alright?

    If you google for MIT Digital Lab manuals, you'll find they have a very nice video about this and other lab techniques. Alright?

    Sublimation is when a solid turns to gas without going thru a liquid, due to the critical temperatures of the material, and is distillation without a liquid phase; dry ice does it, alright?

    It is iodine, because iodide ions form dimers, elemental I2, ines, Alright.

    Alright.

    John

    :P

  • is this your real voice?

  • Is Iodine Gas toxic?

  • @TheTrueSong Because iode belongs to the same group of elements like chlorine gas I presume the two elements are compareable in their "healthiness".

  • please tell me how many milliliters fits into the round flask

  • Can anyone tell me whats the size of filter paper

  • Nice

  • Iodine pretty! Pretty pretty purple!

  • ill guess that that cloud of purple smoke is deadly xD

  • NurdRage, is there any difference at all in the result between the potasium and sodium iodides and if so which one works better.

  • good vid!

  • I noticed that the iodine vapor severely discolored your sign. I'm wondering if you could do a video on the process of cleaning the fume hood after such a reaction. Perhaps equipment maintenance is beyond the scope of your videos, though.

    Thanks.

  • as its supposed to be some kind of nerdy shit, it's actually cool! good job!

  • *laugh* that has to be the messiest lab technique I've ever seen! Its almost exuberant in the degree of mess !!!!

  • oh I had some iodine and I thought it was potassium pomagranate. I added water to the crystals and the solution turned brown, so I guess I need to make some potassium pomagranate.

  • I don't know if you've answered this yet and if you have don't bother:

    When doing the reaction with Mg at the end could you do that in a ceramic dish or something and place a cold round-bottomed flask over it to recrystallize the excess iodine gas given off? Or is it just too hot?

  • Can I make Iodine by adding CuSO4 to KI?

    2CuSO4(aq)+4KI=2K2SO4(aq)+2CuI­2

    CuI2 then decomposes to CuI and Iodine.

    2CuI2=2CuI=I2

    I2 would be purified by sublimation crystallization.

  • I would chill the H2SO4 before adding it to the KI. Less loss of I2 to the atmosphere, BTW is the the reaction H2SO4 + 2I3- -> H2O + 3I + SO3-2?

  • its really sad that in my country you cant buy cemicals only anymore as a civil person

  • @Noxnamer Agreed. Anyone that wants to pursue criminal activity can almost always find a way around the laws meant to stop them. In effect, only the innocent are punished by such laws. And, perhaps I am in a minority to believe as I do. But, I feel that consentual crimes are not crimes at all. If something is not right to do it will come with its own automatic consequence.

  • thanks!

    

  • Could bromine be produced the same way (substituting a sep funnel in the filtering stage?)

    i.e. Sodium bromide --H2SO4--> Br2 (and trash)

  • @jody4403363881 Absolutely... I've done this myself, alhough I would reccommend distilling it for a higher quality product if you have the proper glass equipment. See my comments on NurdRage's other iodine video for more details

  • @theyellowdartALT Probably best in a fume hood or out doors? :) I might give this a shot. I do not have a complete element collection and bromine is one of the missing pieces. If memory serves correctly, an alkali halogen salt with a nonvolatile acid can give a corresponding halogenic acid as well. In otherwords, Phosphoric acid + sodium bromide = (throuigh distalation) hydrobromic acid. H3PO4 + NaBr + (heat) = HBr (At least I think)

  • @jody4403363881 In order to make HBr you would want to use dilute sulfuric acid as concentrated H2SO4 will oxidize the HBr initially formed directly into Br2. The inclusion of H2O2 in the process is essentially just to guarantee that the HBr does indeed get oxidized. After distillation the HBr can be further dried by extraction with conc. H2SO4 to remove any water that may have distilled over with the Br2 and to oxidize any remaining HBr.

  • awesome!

  • I noticed that when you did the vaporize part some iodide vapors escaped.... is that necessary cuz it creats pressure? or only cuz the flask had a spout?

  • @Someonationification the impurities may vaporize and overpressure the container, so it's a good idea to let some out. As such this experiment should be performed outside or in a fumehood.

  • @NurdRage Is this type of iodine give people cancer?

  • @NurdRage Is it necessary to use concentrated sulphuric acid? Presumably the acid acts as an oxidising agent as well as an acidifying agent. I used to make iodine by dissolving KI in water, adding dilute sulphuric acid and then hydrogen peroxide to oxidise the iodic acid to iodine. I then heated the mixture in a beaker to sublimate the iodine which then solidified on a round bottomed flask filled with water placed as you've done in your vid. Simpler and less dangerous.

  • What video edditor do you use becoase i want to put a video in a video if u know what i mean. Please reply!!

  • Hey Nerd Rage,Is the purple smoke/vapor toxic?

    Please reply.

    Thanks

  • Does anyone know of a web site that seels good quality chemicals and ships to Australia?

  • also whats the concentration of the acid?

  • does it work with HCl instead of H2SO4?

  • @LedKenji666 I would guess not, because there are two things the sulfuric acid do: it acidifies the solution and oxidizes it. I would think maybe HCl followed by an oxidizer such as bleach would work.

  • what is the chemical equation between NaI and H2SO4 and how to make the iodine powder ???

  • Hey, I like the guy who wants to make hydrogen sulfide, a few posts below lolol, it's gone kill you buddy!

  • i'm allergic to iodine

  • thats cool. can you take decolorized iodine and make it pure

  • What is the wierdest colour you've seen in a gas cloud?

  • This guy sounds like jigsaw from saw!

  • @hello34528 That explains everything

  • @hello34528 it probably is jigsaw! :P i always wondered if he did actually die! but now i know he's teaching science on youtube! Go jigsaw!

  • @hello34528 The key is inside the Iodine

  • is there a way to store the iodine somewhere? or theres only the heat that can change it into gas again?

  • what is the easiest way to make HI (the cleaner the better)?

  • epic :P

  • Is it possible to use 30% HCl and then boil away the water?

  • But wait, after mixing H2SO4 and KI it should give K2SO4 and HI.

    HI is unstable or what?

  • @Chmielok HI is a strong reducing agent and concentrated sulfuric acid is an oxidizer so they react with each other

  • i like this method the most out of all other methods of making iodine

  • Amazinggg! in my opinion, anyway haha. Was very interesting to watch, im surely going to do it sometime. Great video.

  • @K5HLR212 Stop watching my videos.

  • @NurdRage Haha, I actually Lol'D

  • @NurdRage I would have pissed my pants laughing if you would have responded with, "Allright."

  • @K5HLR212 please stop complaining! your breaking my concentration.

  • How many grams of Iodine per grams of KI could one expect to get using this method? Are their any techniques we could use to minimize losses?

  • @aCagedApe in theory you could get all the iodine, (you can calculate the stoichiometry) but in practice there will be some loses. I never really measured yield to be sure.

  • @NurdRage It looks like a LOT of iodine is lost just by looking at the color of the wash water you throw out. Can't you just filter the entire solution from the beginning?

  • are the gases produced by this reaction nitrogen dioxide or some other brownish toxic gas?

  • that is like way cool, is iodine metal?

  • Hey, I found another way to make iodine using tincture of iodine, HCl and H2O2. I combined them in a ratio of 1:1:2

    (TOI to HCl to H2O2) and it worked! Iodine precipitated out!

    but, I'm still curious.... what is happening in this reaction?

    If you could give me the equation that'd be great :)

  • @japanesepoptart

    i think that the tincture contains potassium iodide, thus adding H2O2 might oxidize the iodide ions to elementary iodine.

  • I'd like to speculate

    2 H2O2 → 2 H2O + O2

    4 HCl + O2 → 2 Cl2 + 2 H2O

    Cl2 + 2I(-) --> 2Cl(-) + I2

    Someone pleas correct me if I'm wrong.

  • very cool man

    can you show the reaction of water poured over sulfuric acid.

    (not sulfuric acid over water)

    thanx and keep up the work

  • I've been having trouble getting this to work properly. My H2SO4 is ACS grade so I'm suspecting the source of the problem is the KI.

    Upon addition of the H2SO4 the solution never becomes paste like and never turns black. More additions of H2SO4 eventually turn it to a thick red liquid.

    I had the same problem with the HCL+H202 procedure except the solution turns a transparent amber.

    The grade of KI is Lab Grade. Any thoughts as to what in the KI might be causing this?

  • if you use iodine supplement tablets derived from kelp, will it produce toxic gases or even make iodine?

  • Does Sulfuric acid has to be strong? Or 25 molar Sulfuric acid works also?

  • yeah becouse every one has potassium iodide (sarcasam)

  • its actually pretty easy to obtain, easier than the iodine itself.

    thus the video for how to convert it.

  • hi nurdrage... im still searching for sulfur so i found out about it that if you add hydrogen sulfide to sulfuric acid (from wikipedia) it will produce elemental sulfur! and sulfur dioxide and water (: a way i found to make hydrogen sulfide was adding aluminium sulfide to water.. but i dont have aluminium sulfide! can you please help me?

  • @TheBubalicious Tincture of Iodine has enough in it to make crystals.

  • Excellent videos!

    Exactly HOW toxic is the gas emmited from the iodide?

  • @Mayokitty7 the gas released is extremely toxic and should be avoided.(hydrogen sulfide) It also can be fatal or cause permanent damage after exposure to very small quantities.

  • does the reaction create aluminum iodide?

  • can you also use a tincture of iodide if so could you please make a video or send me a e mail on how it can be done

  • could you make iodine from electrolysis of potassium iodide

    KI aq = I + H + KOH

  • no, iodine reacts with KOH

  • couldn't you just filter the slurry every time instead of pouring the liquid off...

  • mgs1234567890:And when are we going to have a new ground zero?

  • i cant stand Sodium Cloride, but i liku potassium iodine.

  • sorry i mean sodium chlorate

  • what a hideous mess!

  • wery well. :):):)

  • this is helpful

    now ima keep some ice water and sodium iodide around the house

    just in case of a radiation leak and i need to make some iodine to flush it out =)

  • Don't take this too seriously, but I find it funny that your name is Lithium.

  • explains his expertise in chemistry.

  • @95Barqs1: I suspect "N. Butyl Lithium" is a pseudonym.

  • so basicallly make the peroxide /acid /PI then when it is done then heat it with an ice flask and the vapur that sticks to the bottom is purified then---tiny or neglible amounts of impurities is not going to kill anyone when I make it into a lugols this can save me a ton of bucks and I can assist others more effectively ---again thanks

  • I did make it but I need to know how the acid is neutralized for internal use ---diluting it would be a solutions but would need a 5-7% strenght so this is where I have to research I can make it with the PI and Iodide crystalss 88gr/44 grams and a litre of water this gives me this ratio---but the other way with the H2O2 and acid and water and PI this is where I need to know how to dilute it

    Again Thanks

  • @HerbsPlusBeadWorks

    If you purify by vaporization as shown in the video then the solid material can be treated as "pure" iodine, no need to neutralize the acid since most of the acid remains at the bottom or evaporates out.

    The tiny amount still contaminating the iodine is negligible.

  • sulfuric acid was over 40% but it may have been the potassium iodide---thanks for the response--I did make iodine with potassium iodide water and sulfuric acid and peroxide wasn't sure if it was good for oral use like the lugols so I dumped it but that did work need to do a bit more research on that one---again thanks!!! I really do appreciate your time with these vids I do them as well
