Physical properties of the Halogens

[Moeggggggggggggggggg]

Bromine looks badass 

[fghsinging]

Iodine is so pretty!

[EmissionNebula]

@fghsinging Iodine is so pretty... in cyclohexane.

[Avington89]

hi my name is anujan this is science and i hate science

678888888888888888888888888888­888

[felixthemaster1]

iodine is a verry pretty thing. but if you stare at the vapour at close range, the vapour condesnses in your eyes making those spikes ands piercing your eyes!

[Oz6102]

@felixthemaster1 You could put the iodine in the glass and then stare at the glass starring at the iodine!

[meteorman96]

ahh yes love a good halogen video my favorite is bromine

[ffdxshow]

you can use bromine to massacre bad people. no bloodshed..lol

[Smellychicken]

lol i've tipped bromine on myself before. only had a slight panic attack!

[cryxpride]

OMG BITCH. U WANNA DIE? BROMINE? LOL!

[quimsolls]

boring i wanted to see fluorine and astatine

[Oz6102]

Fluorine Atacks Glass. And Astatine is Radioactive

[Oz6102]

Maybe if you want Flourine and Astatine

Flourine in Quartz Glass

Astatine in Lead Glass

[Chmielok]

@Oz6102

F2 doesn't attack glass, HF does.

[bokitoo1]

@Chmielok

actually fluorine does attack glass, in the presence of moisture to form silicon tetrafluoride, it will not react with dry glass though.

[xjkgx]

somedudeinva is correct :-) its strong only under ANHYDROUS conditions i should have been clear on that! good job! ;-)

[xjkgx]

Hydrogen Fluoride HF is NOT a strong acid because of the great polarity of the Fluorine causing lots of hydrogen bonding in HF it is the exemption of the halide acids

[somedudeinva]

Anhydrous HF actually has a Hammett acidity function of about -11, comparable to anhydrous sulfuric acid.

When anhydrous, HF is effectively a strong acid, but really more like

2 HF --> H+ and HF2-

In aqueous solution, it is weak, but people tend to call it "strong" simply because it is so destructive to many materials, but the destructive power arises from the bond strength of various elements with F, rather than the acidity.

[mewrox99]

@xjkgx

Hydroflouric acid is weak, however anhydrous HF is extremely strong.

[Lamborgini1118]

@xjkgx Technically HF is a weak acid, but that doesn't mean it is not powerfully acidic. It can easily melt through human flesh. Wiki it.

[EbiTron]

@xjkgx HF is indeed not a strong acid, but it does behave like one!

[00bean00]

@xjkgx That is a technical term, but HF is extremely dangerous. A splash the size of your foot is enough to kill you if you are not treated almost immediately. The acid soaks down into your bones (without burning you) and draws the calcium out of them and out of your bloodstream. Without calcium, soon your muscles, heart, and nerves will stop working.

[xjkgx]

@00bean00 you are indeed correct dear sir! the fluoride ion wil wreak havoc in your body since it is the most electronegative element, it will bind to anything to achieve its stability including ripping of Calcium ions from your bones... :)

[xjkgx]

elemental Bromine is neither acid nor base Br- ion is a weak conjugate base of strong HBr acid and thus Br- is not a strong base when compared to OH- ion for example the oxidizing ability decreases down the group so Cl- ion is a more reactive base than either Br- and I- but in comparison, the halides generally are weak conjugate bases of strong acids

[sciencoking]

i like the smell of low concentrated bromine...

[sciencoking]

what? did you smell that? it smells awesome!

[TheDrkKnght1988]

mix magnesium with bromine, it creates a hot flame.

2Mg + Br2 ===> 2MgBr

[TheDrkKnght1988]

Is Bromine a strong acid or base? It is said to be corrosive.

[chiodos132]

yeah, pure bromine burns your skin off.

[mewrox99]

It reacts with water to make, hypobromous acid, and hydrobromic acid, the latter is a very strong acid

[dragonridley]

@TheDrkKnght1988

No. But It can be a strong oxidizer

[pyropakman]

Why don't they have fluorine here?

[dragonridley]

@pyropakman

Fluorine is to reactive to work with safely.

[MrGameAndWatch00000]

i ask that too

[johnsmith777710]

It wouldnt matter because it costs $9 per ml

[indiaman1970]

Astatine , although a halogen,is very rare.The reason is, it radioactive with a half life period of approximately 8 Hrs.Scientists believe that if we dig up the whole earth,we will find not more than a gram of Astatine.

[Dethlicon]

I see no Fluorine or Astatine!

[Sebbass69]

does anyone know what the tubing between the flasks is made of?

[GingleGangle1]

what about the fluorine?

[MarkRoks07]

Thats way to reactive,it can set your hand on fire by touching it.

[GingleGangle1]

Would you light a candel under Cl2 to see if it be red?

[mewrox99]

I have done that, It burns with a very dark sotty flame, the chlorine is not a strong enough oxidant to oxidise the carbon in the candle, so soot and hydrogen chloride are produced

[legominifigure7]

too hard to find

[ManlySlut]

There's no way cheap easy way to contain it.

They can't keep it in a glass or a plastic bottle as it would react with both.

[acheing123]

Cool. Never knew that.

[keckium14]

FelixB91:

Fluorine is so reactive that and it is very difficult to handle. It will even react with glass in the test tubes etc.

[FelixB91]

Why didn't you tell us about flourine?

[quantumQresonance]

get some dry ice and alcohol, take a dry wine bottle and imerse it in the dryice alcohol bath, make a chloring generator from sulfuric and hypochlorite and pipe the gas into the wine bottle til it is half full of liquid chloring gas. Cork that shit let it warm up a bit and chuck it at the concrete. lol

[TornadoMan86]

Anyone wonder why the bromine bottle has a giant capital "F" in blue?

[jmmatos23]

It could be a design for the brand of the producer.

[jamiepoultonadult]

it means 'Fucking dangerous'

[YourtubeTV1]

hey for once i found yours jay, then again you just sent it me

yellow liquid? piss?

[crazyboy0602]

Fisher Scientific sells a large range of chemicals. That giant F is their logo.

[skunch]

very interesting.

[Gadolinium158]

thes is stooped kemistrey n math r dum n nowun kares r evin needs 2 no abaowt it

[jmmatos23]

Kid, its time to grow up, how could we live without math or chemistry? u dont look like a super genius, just look at ur comment.

[Jared2thabonee]

Please learn to spell/talk.

kthx

[flin1411]

i like the last 1 the most =-)

[TornadoMan86]

Iodine sublimes when heated on a hot plate.

[flin1411]

omg were in science class again =-|

[ahmad2009aqa]

boring..

[Trevnyah13]

waitwait so why do the ppl makin meth do the whole freezing thing with peroxide and hcl when they can just do what they showed in the vid?

[loveu4eva07]

boring..

[Greenhorn82]

Then don't watch it.

I think this video, and the others like it, are absolutely fascinating.

[Basco36]

were can i get bromine?

[parduspilot]

Bromine is in seawater and commercial bread. Bromine blocks the iodide receptor in the thyroid gland which could lead to hyperthyroid or hypothyroid.

[Basco36]

well yes its in seawater but i mean were can i find pure bromine.

so your saying bromine is very bad for you?

how bad?

[SSJLIGHT]

Anything in concentrated amounts can be bad. Mountain Dew and other clouded soft drinks such as orange soda have brominated vegetable oil in it.

[SSJLIGHT]

Btw Bromine is very nasty shit to work with. Touching it can cause painful blisters that slowly heal over the course of days.

[Basco36]

how do you know.have you ever worked with it before? i have some Br in a volimetric flask im not really sure what i should do with it

[SSJLIGHT]

Yes actually. And if you pretty much do your research on Bromine over the internet you will find that it will tell you the outcomes of coming in contact with it. Unless you're at home there should be a container that speciies disposing of bromine in it. Never ever pour chemicals like that down the sink. Or if you have sodium bisultfite around react it with bromine in water to neutralize it.

[hekticnate69]

fukn hell u guys r nerds

[Romanacer]

interesting,but fluorin would be very awesome.

[SSJLIGHT]

I take it Flourine is too dangerous to work with and Astatine is too rare.

[parduspilot]

If I'm not mistaken, flourine can etch glass.

[SSJLIGHT]

Hydrofluoric acid can eat glass. So they store it in plastic or wax bottles.

[turtle9922]

does anyone know the physical properties of iodine when you eat foods? like how doe it help you(it reacts with something?) im sure it does, but how? and what?

[SSJLIGHT]

Iodine is in iodized salt. It helps to prevent Goiter and its nutritional value is that a hormone can be made with it by the thyroid called Thyroxine where Iodine is part of the molecular formula of the hormone.

[99yrs0ld]

omfg  u retard its I-O-DYNE FRIGGIN LEARN TO PRONOUNCE THE WORD MY GAWD

[SSJLIGHT]

Actually there are many ways to say and spell certain things. It's more of a preference of the region the chemists reside, resided in, or worked in. People say differently in many areas of Europe as we have our own way here in the US. Some places however are so anal about naming in cases where people would order Muriatic Acid and they Hydrochloric Acid named and would send it back b/c they asked for Muriatic.

[pchk1]

aw come on, it's I-O-DEEN not I-O-dyne!

[madpaintbalerx]

In Britain, not the USA.

[pchk1]

Like the USA is for double-standards?

Funny the very same she pronounced chlo-REEN and bro-MEEN earlier in the video.

I wonder if she'd say fluo-ryne or fluo-reen . . .

[TomXXL]

I love chemistry ;)

[easyas4]

lol dooch

[batubursa]

fuk it

[szymonbartus]

Love it.
