Elementary productions: Preparation of liquid Chlorine gas

Chlorine gas has a boiling point of "only" -34,4 degrees Celsius. As Dry Ice sublimes at -78,5 degrees Celsius, Chlorine gas is easily condensed in a test tube submerged in a bath of Acetone and Dry Ice.

The Chlorine gas is produced by adding Hydrochloric acid to Potassium Permanganate.

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 =)

my chem teacher just adds HCl to bleach instead

[mabakken]

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

[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.

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

[Riley0143rsj]

@diapysik Oh. Im 12.

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

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

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

[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

@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...
