Ammonium Metavanadate

Hey guys, I am not sure if you can see the last post I did of this. 

There was a mixup and I think Patreon didn't charge or something so I am reposting it. If it bills you twice, be sure to cancel one of the charges! I will try to fix it myself though,

I will try to do more inorg when I can. I will be regenerating mercury metal from the sulfide waste eventually.

Thanks for doing an inorganic synthesis. Not all preparative chemistry is organic.

I think you might be able right about the common ion effect. Also, I didn't even think of doing a redo titration. Maybe I'll do that!

I don't have any real theories about the solubility issue: the behaviour of the various discrete and polymeric vanadate species looks pretty complex. For the crystallization, I would guess that if you left it to crystallize for longer you would have got the same amount as when adding the ammonium chloride. The ammonium chloride would have accelerated the crystallization through the common ion effect. Have you thought about doing a redox titration of the product to determine the purity?
