Any chemists in the house ?

Anyone know if Iridium Pentafluoride is hazardous to human health ?

m8 of mine just phoned up asked if this stuff was dangerous, sounding rather panicky then suddendly hung up...

Tried calling him back to ask WTF and get "person unavailable" network answer.

pretty sure iridium isn't that reactive... dont think it occurs much naturally though. It could be radioactive It's close to gold in the periodic table.

well, I hope your mate is okay...

I'm no chemist, last time I sat in a chemistry class was about 7 years ago, but iridium itself is a platinum like metal, really hard, and really unreactive, therefor not toxic.
Hoever, iridium can be reactive to certain molten salts, and that's probably how Iridium (V) fluoride is made.
Haven't been able to find anything concrete about that stuff, but Halogens (like fluoride and chlorine) are toxic in large quantities (there is a slight percentage always in the air we breath which doesn't do us any harm)

I've got no idea what the combination of the two does. It appears to be a yellowish crumbly substance. not gaseous.

Looks like your friend is going to find out the answer one way or another.

a quick google suggests that pentafluorides are hazardous.
however, there is no mention of iridium pentafluoride specifically is hazardous.

i hope your friend is ok.

I thought that was the new Satellite phone, the one with that cleans your teeth as you talk.

Any word yet?

thats evul lol

i think if u cant buy it in mcdonalds then going by the law of science we can conclude it must be hazardous.

I thought most of the stuff you could buy in Mac DOnalds was hazardous to health?

Flourine you mean? flouride afaik is quite solid and used in toothpaste no?

there's a difference between fluor and fluoride, one is non-toxic and good for the teeth, the other pretty toxic

same as methanol and ethanol. the first will make you blind, the other will make you blind for female uglyness

rofl , anyway, the flourine i ment is where you said the halogens, since flourine id guess is a gas, and flouride id say wasnt
