Hi, This may provoke a chuckle; or more likely, give you insights into the idiot mind.
I bought a large bag of kno3, only to find that it also contained 4% te.
The "te" in lower case letters on the bag told me that the kno3 was contaminated by Tellurium. 'Right, I knew te was metallic, but the name. . . Perhaps named after Edward Teller. Teller, the father of the H-b**b. This must mean it's possibly radio-active, or toxic; probably both.
And what was a poison doing in fertiliser, anyway?
Finding that tellurium was indeed toxic, I started getting paranoid about handling the stuff.
I could find no mention anywhere of it being used in fertiliser.
The thick plottened! Much later(days)I examined a packet of ordinary fertiliser, and looking at the list of TRACE ELEMENTS, I had a little "eureka moment".
'Yep, that's what it was, finally; bloody trace elements, like mg, cu, etc.
'Luckily, it can be removed by recrystallisation.
'Seemed funny at the time.

hi, my first post.
does anyone know the purity (naclo3) of "Morgan's" weedkiller.
if there's a contaminent, what might it be and can it be removed by fractional crystallisation?
btw it's a better oxidiser than kclo3 because the na atom is much smaller than the k atom.
if you can keep it dry, you get more bangforyourbuck.
'pity about its hygroscopicity.
