Elementary productions: Preparation of liquid Chlorine gas

[lexichronicle2]

sounds like he has the cooker hood on full, but I bet the place still stank like a swimming pool :P

I've done it before as well (generated large volumes of it); enough that the flasks turned green.

if even a small amount escapes, the smell is unreal.

[HazMatLabz]

so since you added HCl to potassium permanganate, permanganic acid was created. If if it were to be dehydrated would it turn into manganese heptoxide?

[diapysik]

i hope you had a ventalator on and no matter what never make it via bleach ammonia cause you could make nitrogen tri chloride by accident

[Riley0143rsj]

@diapysik Bleach and ammonia doesnt even generate chlorine gas...it generates chloramine gas.

[diapysik]

@Riley0143rsj i posted this when i was like 16 n stupd

[Riley0143rsj]

@diapysik Oh. Im 12. 

[diapysik]

@Riley0143rsj lol since you said that i posted that when i was like 11 now im 12

[bassplayer2161]

well looks like im moving to Norway!

[neddy17]

one could also use manganese dioxide, easily obtained from batteries instead of permanganate, if they couldnt find it

[11to]

danmark?

[slateflash]

Cool! Cn u do it with fluorine?

[liquidoxygen0]

slateflash: You can do this with pretty much any element with the right equipment, but it's much more difficult to do it with Flourine because it has a far lower melting point than Chlorine does. While Chlorine's melting and boiling points are -101°C and -34°C, Flourine's are -219°C and -188°C.

[waskaman94]

if you can cool it to the boiling temp uf fluorine

[Masalmeh321]

@slateflash This is possible to do with Fluorine but very hard because of extreme reactivity. Industrally, liquid Fluorine is made though for things like Tungsten carving etc...

[Sub2Me4ASub]

how do you dispose of what's left of the permanganate/hcl reaction? or how do you stop the reaction from producing dry hcl?

[Sondretheman71]

ohhmy gosh, ITS YELLOW! just kiddi'n, try to smell on salmiac!!! i did it and it felt like my head was goi'n to blow up man x]

[carlitoswey2008]

i thought chlorine gas was dangerous if u breath it..

[derkozten]

Well... it actually is!

[team20111]

fills your lungs up with fluid and your drown to death

[contentlocked99]

actually that fluid IS your lungs, it dissolves the sacks in your lungs that bring oxygen to the arteries.

[thecrazychemist]

Not quite - the chlorine cause pulmonary edema; check it out

[srbija23232323232323]

Why does the chlorine gas condense in a hot test tube. Shouldnt it stay in gas form?

I just remembered. Chlorine gas has to be heavier than air because Germans wouldnt use it in WWI

[mabakken]

The test tube is not hot. It is submerged in a Dry- Ice/Acetone slurry. This means that the temperature of the test tube is -78,5 degrees Celsius, more than enough for the Chlorine to condense =)

[srbija23232323232323]

Ok, I thought that that was boiling water. I was like wtf

[RicardoGarciaPino]

weird, why chlorine as gass is grenish and as liquid its yellow ?!?!?!

[JoaumlEphgb]

Great =]!

[Bernler75]

Is chlorine gas heavier than air?

And what can you do with liquid chlorine gas?

[derkozten]

Yes, it's heavier.

And volatile gases are made liquid more for transportation purposses than industrial processes per se, where gas phase is preferred.

Liquid chlorine is too concentrated, too dangerous.

[420chazz]

what can you do with liquid chlorine gas?

drop sodium in it! =D nah don't do that.

[usemyillusion9]

my chem teacher just adds HCl to bleach instead

[mabakken]

That is one way to prepare Chlorine gas as well...:)

[usemyillusion9]

nice vids btw tanks 4 putin em up

[derkozten]

It is another way, but the KMnO4 yields much more Cl2, being a solid reactant; bleach is a somewhat diluted hypochlorite solution.

"Bleach" reaction:

ClO(-) + Cl(-) + 2H(+) -> Cl2 + H2O

Permanganate reaction:

2MnO4(-) + 10Cl(-) + 16H(+) -> 5Cl2 + 2Mn(2+) + 8H2O

[usemyillusion9]

lol , it wasnt very diluted when i sniffed it ! i had a blocked nose at the time but after i could breath fine apart from the back of my throat swelling up , its wasnt very nice lol

[derkozten]

lol, I understand it. It's just like when I first smelled (smelt?) ammonia from a "diluted" solution. It's horrible, you can feel ammonia "running down" through your lungs.

What I meant is that solid KMnO4 has much more potential for creating Cl2, given there are more moles of reactant, compared to an equal weight of bleach.

[stylcd]

where do you get the dry ice?

did u put it in ethanol?

[mabakken]

Suppliers of gas usually carry Dry Ice. That's where I got it. The dry ice in this video is put in Acetone.

[danagol1985]

If you were to place a small ammount of sodium into the clorine liquid would it have a strong reaction, or must the chlorine be in its gas state to be reactive? i am inerested

[mabakken]

The chlorine is much more reactive in its liquid state as it is more concentrated. If one were to add a piece of Sodium to it, it would explode!

[mingmingnak]

dude? where do you get all these chemicals... arnt they like rediculously expensive..... all i do is make my own...from random...house hold items

[mabakken]

Yes, it is expensive, but every single chemical used in this experiment is OTC! (at least in Norway)

[vmelkon]

What is OTC?

[mabakken]

Over the counter =)

[Basco36]

you can also make chlorine through the reaction of HCl and calcium hypochlorite.

[thecrazychemist]

I'm guessing the bubbling in the beaker is due to dry ice? not because the electric hob is on lol :P

[mabakken]

Yes that would be the dry- ice. =)

[jmmatos23]

will the liquid turn gas again at normal temperature?

[mabakken]

As the boiling point of Chlorine is - (minus) 34,3 degrees Celsius, the liquid Chlorine will quickly boil into a gas a room- temperature!

[jmmatos23]

awesome! thanks for this video, i was wondering whats the easier way to make chlorine :)
