According to that MSDS sheet, iodine is solid at room temperature? Since unstable stuff would encompass solids that turn into two stable gases.. iodine isn't naturally a gas. But I suppose with the heat of a boom it would be a gas really briefly, then become solid again.

Ah, good point. There will be plenty of heat at first, but its going to diffuse really quick, maybe too quick to see, but at some point the laws are followed. Love that word, thermodynamics. Always trips me up  ;D

Iodine
« Reply #4 on: April 26, 2004, 05:12:37 PM »
Iodine is most definitely a solid at room temperature.  However, it easily sublimes into a beautiful violet colored vapor at normal atmospheric pressure.  If you take some Iodine crystals and just put them out in the open air, over time they will sublime into iodine vapor and your crystals will be no more.  All the halogens tend to easily form vapors if they aren't already gasses at room temperature.  (Bromine especially.  That's what makes it so difficult to contain.  The liquid will quickly form a vapor and fill up any container it's in, then proceed to eat through said container).  If you heat up solid iodine, you'll quickly see it turn into the gaseous form.  It's in this form that it's the most dangerous as it's easily absorbed into you lungs and mucus membranes.  With bromine you'll at least know right away that you've got some on you as it will quickly start burning.  With iodine, you may not realize that you had some on your skin for a good while until you see a big red spot form where the crystals had been lying.

Do all halogens behave this way? And all halogens are caustic? Pretend I had some iodine crystals, I should be able to store them in a glass jar (with a good lid), and if they turn into gas they probably won't eat through the sides? Or I could always overpressurize the jar and they definantly shouldn't sublime.

In a closed system they won't sublime to an extent where you will have to worry about that..

Iodine won't eat the glass jar, but it might eat the lid.  Also, it will sublime through the lid's fitting to the glass, although it might not be that quick.  Unless you flame seal it in glass, I have yet to see a fitting that is tight enough to keep iodine in.  It sublimes through everything, including vacuum grease on a ground glass joint (surprisingly fast, too).  It leaves stains, but they sublime away, too.  In a closed system, any difference in temperature or concentration may promote the sublimation of the crystals around the inside of the flask/ampule/whatever.  Not a big deal if it's sealed.

I assume jdurg has some iodine, given his element collection. From reading the MSDS sheet, sounds like its bad for you, and given that it sublimes... not good to play with. So if I want some, pretty much get an ampoule and just keep it sealed for collection sake. Now doesn't lye contain a lot of iodine in it? What bonds to it to keep it nice and inside the jar?

Iodine is used as a sterilizer for medical stuff. You can buy medical iodine in plastic bottles, its about 2% iodine and 3% iodine salts. It works because its so reactive that even in small amounts its still effective for what they use it for.

When looking at MSDS sheets, remember one thing; they exaggerate for safety's sake.  If you've ever read the MSDS for water, you'd be kind of shocked at how dangerous it makes it sound.  Of all the halogens, Iodine is the least reactive/dangerous.  My ounce-and-a-half of Iodine is contained within a fairly small amber-glass bottle with a Teflon-cone screw top cap with Teflon tape wrapped around the threads.  The Iodine has been safely secured in there for about three months now without any odor or visible leakage coming from it.  (Unlike my bromine which has a mild bromine odor coming out of the bottle).  If you drop a crystal of Iodine on your skin and you promptly remove it and wash the area, there will be no damage.  It's only if you forget to remove it that it will begin to damage your flesh.  (Bromine, on the other hand, will immediately begin to eat away at your skin.  It's a really nasty substance and I'm thinking about taking what I have and heat sealing it into a very large ampoule to compensate for pressure changes).
