Ok, so.....
Total expenditure: $18 for the ethanol --- yield: approx. 5 teaspoons.
But I know what went wrong. When I added the ethanol to the water+NaHSO4 solution,
the latter recrystallized upon dilution with ethanol, which I mistakenly took for precipitation.
Right now I've been boiling a mixture of ethanol and NaHSO4 for 2 hours, and will
continue to do so. I still believe in the method. Perhaps this is wishful thinking on my part, but the alternative is dry destillation of FeSO4 in my
propane furnace *shudder*.
The irony of the whole damned think is that
I only need about a deciliter of sulfuric acid,
to make nitric acid out of it. (Goal being to
solve platinum in aqua regia, precipitate onto diatomaceous earth and henceforth
use good, old-fashioned burning of sulfur
using the contact method.
My nitric needs are still at least a week out
of fulfillment. I'm constructing a Birkemann-Eide reactor to make NO2 from air. The prototype, which was destroyed in an accident, proved that
the method works.
Sigh.

Much better yield this time. 0.1 liters of fumigating H2SO4.
I suspect that if the NaHSO4 was kept in
heated ethanol (say 70 degrees) and constantly stirred during a couple of days,
the yield would increase dramatically.

Birkemann-Eide reactor
Whats this?
No Google results...

I don't know what kind of termites you have but don't do it! If you fumigate with H2SO4 Your furniture will melt!
Arguing on the internet is like running in the special olympics; even if you win: you\'re still retarded.

Fuming. It should read "FUMING", not "fumigating. Look, it was late and English is
only my second language.

Organikum: It's basically a lightning discharge
reactor that splits the bonds between the
O2 and N2 molecules in normal air.
N2 + O2 --> 2NO
NO has a strong affinity for grabbing an extra O out of eccess air, giving:
2NO + O2 --> 2NO2
which, combined with water, gives
2NO2 + H2O --> 2HNO3 + H2
The method was invented in 1905, I think,
and the only reason it's not used today is
that it's VERY energy hungry.
In my prototype I used a neon sign transformer to do the discharges, and
it worked. 9kV, 60mA. That's over 500W of
power. Main problem is to cool the electrodes and the reactor.

Nitrogen dioxide usually reacts with water to form:
2NO2 + H2O <---> HNO3 + HNO2
This mixture decomposes and some of the HNO2 goes to NO and that will react with ambient oxygen and re-dissolve and so on and so fourth.

BromicAcid: The discharges form some O3 as well. But you're right. The end product, however, should be HNO3(aq), right?

Perhaps I should mention that my system uses 3 bubblers in series, with the gasses from the last one being blown out the window through a PVC tube.

Can you please quit making new threads and posts?
To me it seems that you are insanely postwhoring! Why does this need a new thread?
Also, USE THE EDIT BUTTON!
One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.
