Iodine from Copper I iodide?
I recently acquired a 50g tamper sealed bottle of Copper I iodide, labeled as 99.999% pure.
How would I isolate elemental iodine from it? Is it similar to isolating iodine from alkali metal iodide? Using sulfuric acid, or HCl and hydrogen
peroxide?
Finally one thing confuses me, the NFPA rating for the copper iodide on the bottle is 101 (health, flam., reactivity) but on the wiki page the rating
is 110.
http://en.wikipedia.org/wiki/Copper%28I%29_iodide
which is correct?

I doubt it would be flammable.
Please remember: "Filtrate" is not a verb.

It seems that the chemical supplier is much more likely to have the proper information on it than Wikipedia is.

Ok thanks, that's what I though. Any ideas on Iodine isolation? I originally bought this to make (Cu Py3)I shown in nurdrage's video,

but there's got to be more than that!

DON'T!! Don't waste such a precious chemical to pursue another that is so easy to prepare (NaI + H2O2, for instance). You've got a 5N compound there,
ferchr*ssakes!

I was confused by this until I looked up the price of Copper I iodide on Sigma Aldrish... this quantity would cost nearly $260. The guy I bought it
from was an idiot... I paid $18 for the bottle, hence not feeling bad about using it. I will keep it tamper sealed for now.
Excuse my ignorance, but what does 5n mean?
and THANK YOU for the warning, I would have thrown $200 down the drain.

99.999%
nearly broke my balls there
i suppose if you were to use it you could POSSIBLY use ascorbic acid as they tend to break copper salts down into metallic copper at some point, but i
think you would need the iodine to be oxidized aswell still
it seems that CuI2 can be made by CuSO4 + KI simply, this would be easy to thereafter seperate out and perhaps be possible to make into copper and
iodine from the dry product?

99.999 % = 5 nines = 5N
Now go and sell that stuff off in small amounts and make a tidy packet!
