Sodium and Iodine

[GTHaroFITBMX]

syringe in background...

[jaytank31]

is that CRACK?

[LOLiver456]

COLLIN. my honors chemistry class is obsessed with you and your videos. keep up the good work! <3

[EthanFoley]

I have that same bowl.

[ampikine]

Where did you get the sodium?

[lexichronicle2]

"WHY THE HELL you was using shorts??"

Wearing trousers wouldn't help much. Standing further back & not poking it would be a better safety measure.

"I hate that people have been brainwashed to think chemistry is only for evil."

The vast majority of people into home 'chemistry' seem to be 'pyros', who don't really know what they're doing. So there is some sense in the government being bothered.

"it takes pressure and heat, like a blasting cap"

Point demonstrated, wants TNT, wants it 'on fire'

[jesusmtzpz]

Very expensive for get a single salt

[Shihab302]

is that a dead fly beside the pyrex?

[LetzteEclipse483]

My favorite line "And that is why we wear protective gear"

[TheMillenniumactress]

Can someone help me understand why these minerals are in vitamins and how come we do not combust? IF you look at vitamins it has iodine, copper, sodium, calcium, zinc etc?

[YukkiHabiki]

its sad one cant learn about science and chemistry due to the US Govt creating a "fear machine" out of the citizens. Science is wonderful and fun, I hate that people have been brainwashed to think chemistry is only for evil.

[michaelively]

oh no it stained the glass, mom is going to be so pissed

[spotlightman1234]

it makes me sad to see all that Iodine go to "waste"

[brain69x]

going purple is no way to go green dude!!!

[smecheru2]

u should tri trinitroglicerin:)tng:) h2so4+hno3+glicerin:) at -10 if u can:))

[aktebayo]

pollution :O

[TheH0U53]

For ur next video u should use Trinitrotoluene and light it on fire!!!!

[ExplosiveScience]

@TheH0U53 Haha, I actually have considered trying more powerful reactions such as the one you stated, but I won't because they are illegal. Modern American society doesn't understand passion for chemistry, but immediately assumes bad or violent motives. If I were to synthesize any powerful compounds, it would be felony. I try emphasize that science is educational and nonviolent, but I also try to keep it fun. Some people still don't understand, I have had a thermite video removed.

[drewnickel]

@ExplosiveScience trinitrotoluene isn't always an explosive, it's used in organic chemistry too, but it wont detonate with fire alone, it takes pressure and heat, like a blasting cap

[lexichronicle2]

@ExplosiveScience "I have had a thermite video removed."

Powdered aluminium has now been removed from the UK eBay, along with other very useful bits of chemistry stuff, purely due to 'pyros' (read, noobs) using it for flash powder and thermite. A guy in the US had a serious problem with thermite not that long ago, which required the authorities help.

This video is far more useful than 'light TNT on fire'. A big sarcastic thank you to the pyros for wrecking home chemistry.

[739199]

@ExplosiveScience I agree. My school had a "science" project but after me and my friends got everything ready (we were basicly copper plating coins with Copper sulfate) but at the last minute our teacher decided it was dangerous. The other group was showing the properties of smoke from burning matches.

[iNFamousAAC]

@ExplosiveScience You should do the chemical chameloen reation :)

[Agentoxedo07]

@TheH0U53 Holy-Terrorist:>*=* cool, what is trinitrotoluen and light it in video the next video?

please!

[TheH0U53]

@Agentoxedo07 Sorry I'm so late, but Google it if you dont know what its is.

[MrChrisrocks1212]

you shoulda stuck your hand in it

[ballonman124]

Like the coat. I'm thinking about getting one myself.

[Nguli34689]

I would like to make a suggestion to you involving the reaction you have demonstrated that showed Sodium metal reacting with elemental Iodine in a pyrex container. My suggestion is that the next time you put the Pyrext container into a pan of ice water to cool off that container to keep it from cracking. That aside, I enjoyed your video and I want to encourage you to pursue your interest in chemistry and science. For someone your age, you are doing a damn good job of handling chemicals !!

[vmelkon]

You should have done this in a closed container, at least it would contain all that I2 vapor or maybe have a tube that leads to some cold water. Nice video, thumbs up.

[ExplosiveScience]

@vmelkon Thanks for watching the video, commenting, and the advice. I actually considered using a closed container, but due to my lack of lab equipment, I was unsure of how to safely contain the I2 vapor without causing a pressure increase. As a result, this is a combination of 7 reactions, I simply assumed the sodium-iodine reaction would be most dominant because it is the most spontaneous and is favored by the concentration of reactants.

[LV07TSK]

oooooooooooo weeeeeee......look out for that I2 vapor.....that s**t will stain the hell outta your clothes!!!!

[ExplosiveScience]

@LV07TSK Haha, that was the best part. When doing another experiment with iodine, I spilled some on a nice cotton T-shirt and was pretty bummed it was ruined. It formed a large brown stain which spread over the shirt, and 20 minutes later was totally gone. When you spill iodine on your skin or clothes, it rapidly sublimes away. I encourage you to try it, it's pretty cool (It doesn't work with iodine compounds, only elemental). Thanks for watching.

[lexichronicle2]

@ExplosiveScience I've got a funny picture I could send you of my hand after a flask of iodine volcanoed it's way out. It looked like I'd had it in the toaster for half an hour.

But if you get any more iodine mess, which you undoubtedly will if you handle it, because it IS filthy, remember that you can wash it off with bisulphite and thiosulphate. Bisulphite is sold at brewing shops to sterilise the demi-johns; sometimes as tablets. It works almost instantly and completely.

[TruFelix]

hehe... nice! ;)

[VampireKick]

DUDE! You just ruined a perfectly nice glass bowl!

[HazMatLabz]

Nice video, good thing it was a windy day to get rid of all that sublimated iodine :P

[freakin1random]

nnneeeeeeeerrrrrrrrddddddddddd­d..........I do this every day and i dont get sunburned!

[ExplosiveScience]

sunburned? I'm not sure what you're talking about, but the lab coat is to protect me from all of the flaming sodium which was shot out of the bowl. Nerds stick to the books; I ski, bike, make explosions on the side, and was homecoming prince. I am a science whiz, but I am not a nerd.

[g3ov4n12]

@ExplosiveScience If you was worry about the sodium WHY THE HELL you was using shorts??

[QuadraticExpansion]

your bowl is long gone. I suggest you buy a new one..

[TheQuantumChemist]

all exothermic reactions that are performed in glass apparatus at temperatures that could potentually crack or break the glass should be done in an ice bath

[SulaFreaks]

spray some water on it

[GeeksRus95]

That will make it worse!

[Frresh123]

cool video can u make more videos like this ?

[ExplosiveScience]

Yes, I plan on it. But I am very busy with school and sports, experiments are very messy and the editing and filming take a while. I will make more, but it could take a while, maybe over Christmas Break. Thanks for watching and commenting.

[Frresh123]

thx this will be very cool :)

[Frresh123]

and btw from where you get the sodium ?

[ignatiuslim]

Really nice video but i agree that a better camera man is needed.

May I know what's the brown thing that was formed?

[ExplosiveScience]

It wasn't the camera guys fault. We used a really cheap camera that was hard to use, and because of the chemical splatter, he had to be very far back. And if the brown thing you are talking about is the residue on the pyrex, that was just iodine. Iodine can be brown, purple, purple-black, yellow, purple-pink, and orangish. I am not quite sure what causes it to vary in color so much, but I think it is related to the crystal size, state of matter, and amount of iodine. Thanks for watching.

[SulaFreaks]

@ExplosiveScience Pure Iodine is I2(grey)

Brown iodine is I3.

And what is your sources for those other colours?

[ExplosiveScience]

No source, just observations. Probably just mixtures of the two allotropes of iodine. The iodine I used was gray, but after subliming and re-crystalizing it can be yellowish orange, and the vapor is bright pink-purple, that can be observed in this video. Thanks for watching and commenting.

[SulaFreaks]

@ExplosiveScience I have recrystallized iodine before and never seen any orange, yellow or any thing else butt purple and gray.

I think something is wrong with your Iodine..:P

[ExplosiveScience]

It might be impure, but it works with all of my experiments so far, I have used it to make NI3, and in your comments, you said it could be gray or brown, and then you said it could be purple or gray, I think part of it is how the color is interpreted. I have seen yellow iodine when it sublimes and re-crystalizes in a very thin layer.

[SulaFreaks]

@ExplosiveScience Sorry I ment that you can see purple.. when it's becomming a gas. Sorry I suck at English:P

And brown is when iodine is recting withitself:

I + I2 -> I3(Brown, pretty dangerus)

[mozo25]

you need a better camaraman. awesome video though i like it.

[ExplosiveScience]

Thanks

[jbrizzzzzle]

colin and kyle. wat nerds!! im lovin it

[minner11501]

did anyone else she biggie smalls after the reaction?

[11to]

cool
