HOMOOO

@Mrschuitema Hebben we die bassie weer!

Ammonium Thiocyanate is a class 1 poison.

Toxicity Class I

most toxic;

requires Signal Word: "Danger-Poison", with skull and crossbones symbol, possibly followed by:

"Fatal if swallowed", "Poisonous if inhaled", "Extremely hazardous by skin contact--rapidly absorbed through skin", or "Corrosive--causes eye damage and severe skin burns"

Class I materials are estimated to be fatal to an adult human at a dose of less than 5 grams (less than a teaspoon).

Go Wisconsin. Wooo! \O/

@howie094 yes, but ammonia gas is given off in the reaction.

@howie094

Addition of a strong base such as Barium Hydroxide to an ammonium salt will release ammonia gas.

[PopViolin94]

isnt ammonia gas toxic?

[Hitsi1991]

How toxic is ammonium thiocyanate

[kindofmagicmike]

@Hitsi1991

15-30 grams can be lethal if you ingest it, and it can cause skin, eye, and lung irritation, but as long as you're not an idiot when using it you should be fine

[freckleface800]

nerds.......haha jk (:

[inquisitiveytm1]

what is the formation of ammonium thiocyanate

[slateflash]

Could sb give me a summary of the reaction pls? Thx.

[bmwsux3]

Did he say 'sodium thiocyanate' ?

That will have completely defferent results.

[ulflaviobria]

a little bit toxic, I think... Barium + CN- isn't so good for man's breathing system such as BaCl2.... but I like the experiment... lol

[DownOnMyLuck]

Yeah, decision to use a thiocynate salt was bizarre.

[PauliusChemLT]

Dumb, its used thyocionate SCN- . Not cyande (CN-) ;) SCN- isn't toxic..

[Mexicandude24]

idea to make a stink bomb ^^

[weipeiwu2000]

i smelled ammonia today in science class and i wanted to throw up from it

[geetarist1]

ammonia smells like cats piss or maybe t-cut car polish not sure if ammonium is the same

[Periodicity]

Ba(OH)2 x8H2O + 2NH4SCN ==> Ba(SCN)2 + 10H2O + 2NH3

Its a great reaction! Done it many times, its a great demonstration of endothermicity.

congratulations, you won the geek of the year price!

[jonmonbuckeye1]

how long does the drop in temperature last?

[gundam178]

wat does ammonium smell like?

[dekjet]

Ohh, hmm, like ammonium ^^

Ask a Chemnistry teacher

[wolboatpo]

it smells like fucking pee

[RetsofNoraa]

Very nice, but I think I'd enjoy it more if I was there.
