My name spells Antoncho
It's a transcription of a russian translation of a mexican derivative of the name 'Anton' - the suffix itself comes from one of Castaneda's books ("- What's up, Khenarcho?"
) Do you by chance know how it spells in the original text?
As for the purity - i think boiling ain't a problem in this case - think of it, why should it? (unless it created much tar, that is).
Unfortunately, your results aren't correct since you used way too much water. Remember, 100 ml aqua dissolves 200 mg CaS)4, and presence of inorganic cations only increases its solubility. So i guess, the real amt of Na2SO4 in your salt is >2 g ---> NaEtSO4 purity < ~60%
It's still good for the next step, just make sure you calculate your NaNO2 amt based not on NaEtSO4, but on the whole weight of the salts' mixtr.
This purity test of course sucks (as i 've noted previously) and won't give you a precise result ever.
I'm eagerly awaiting your results, PM me if you have any Q's you think i could help with (as this seems to bee just a conversation beetween us two at this point)
Bee sure that a)your NaEtSO4 is dry b) NaNO2 is melt-dried (BTW, it's better to shuffle it up beefore it completely solidifies, otherwise you're gonna have a hard time scraping it off the dish) c) you mix the ingredients in a coffee grinder as finely as your patience (and the grinder) will allow.
