Catalytic oxidation of ammonia

This is oxidation of ammonia by oxygen catalysed by warmed platinum wire. Oxygen is bubbled through ammonia solution, in which it mixes with ammonia gas present. The reaction causes the platinum wire to glow, and the hot wire ignites a mixture of ammonia and oxygen.

WTF are you doing, not wearing gloves?!

@FreeTheRadical well im sure it couldnt be but i had a fine metal powder that would not dissolve in nitric and sulphuric acid so its possible that it is platinum or any other inert catalyst metal they use like rhodium or paladium

[FreeTheRadical]

@Rannyfash correction:

IF it is...

didnt mean to sound so sarcastic btw

[FreeTheRadical]

@Rannyfash how did u manage to get it out in a usable form? as far as i understand it its not really accessible in a way that can easily be used even as a lab catalyst... it it is id love to know but it somhow seems doubtfull

[Rannyfash]

@FreeTheRadical i stole about a couple of grams from my neighbours catalytic converter

@evansp12 so how come the ammonia isn't just burning into nitrogen oxides?

[vmelkon]

@adriankocian There would be some N2 formed as well.

this is a very cool video, its great to see chemistry demonstrated in such an interesting way.

its just a shame that platinum is so damn expensive.
