Ampoule suggestions

thesmug - 8-2-2014 at 23:24

I recently found an ampoule that I didn't know I had and have become obsessed with finding something to put in it. What do you suggest I should put in it (I am already considering iodine)?

liquid chlorine
bromine
mercury

what do you have lying around?

I'm currently awaiting a very large order of chemicals which I expect to arrive soon, so there will be more possibilities then. I was considering making bromine but it seems too dangerous. How do you make liquid chlorine?

MnO2 + 4 HCl -> MnCl2 + 2 H2O + Cl2
or
NaClO + 2 HCl → Cl2 + H2O + NaCl (if im not wrong theres also a byproduct of chlorine dioxide)

you could condense the cl2 gas into a liquid at -34'c or at 740 kPa

do note the safety hazards associated with working with chlorine

Uh...

Dont you think making (and storing) liquid chlorine would be just a smidgen more dangerous than bromine? Chlorine has a b.p. of -34 degrees so there is significant risk of the ampoule just bursting. I would try condensing the chlorine using dry ice/acetone, or liquid nitrogen if you can get hold of it.

stick with iodine :P

Yeah, I guess I'll just take the above suggestion and make iodine.

Air or moisture sensitive chemicals are also prime candidates for ampouling. Some time ago I made some hexaaminenickel(II) chloride, which is a bright purple compound that's fairly easy to make. If you leave it open to the air, it loses its ammonia ligands (if I'm using that term correctly) and reverts back to green hydrated nickel(II) chloride. I sealed mine in an ampoule to prevent this, and it's still nice and purple.

How about sodium, or other group 1-2 elements. You're not just considering elements right, because there are all kinds of great looking compounds that would be good for putting in an ampule.
NO2↔N2O4.
Any copper compounds.
Potassium permanganate.
Ect.

[Edit] Chlorine is not undoable, you just can't put it under any pressure, so unless your ampule is very big, the color will not be very visible.

Which copper compounds would be necessary to keep in an ampoule?

Where could I find documentation as to how to make this?

[edit] Nevermind, found a video :P

[edit again] Oh, I found your video! I didn't see your username at first!

I don't know, I wasn't thinking of something that would be necessary to keep in an ampoule, just something that would be cool looking, same with potassium permanganate.
I'm sure there are some copper compounds that react with air.

It has been my understanding that most copper compounds look the same (blue), are there any that are significantly colored?

Copper chloride looks a bit green blue.
Copper ammino complexes look dark blue.

There is red Chevreul's salt, brown anhydrous Copper (II) Chloride, white Copper (I) Chloride, and some green copper (II) salts. Of course this is a bit tough for me to back up (I am colorblind :( ), so I am taking Wiki's, SM Members' and/or Youtubers' word for it.
