HNO3

[PhAINTo]

I have been looking for potassium nitrate but the only thing I could get was
HNO3 (40%)

Now I'm wondering if the chemical reaction

HNO3 + KOH ----> KNO3 + H2O

is safe to do because I know that this kind of reaction produces a lot of
heat

and second if you can dry out the KNO3 by heating the solution.

Or are there better things to do with the HNO3?

You can use KCO3. You must add a little bit of HNO3 until CO2 emission
end.It'a producction of heat but not a lot. After you can heat and
concentrate and cristallize KNO3.

P.S. Excuse me for my terrible english!
I'm an italian student in chemistry.

Seems like a waste of good acid.

Indeed. KNO3 usually is available cheaply and in decent purity as a
fertiliser. HNO3 is cheap in large quantities, but if you're getting it in
bottles from smaller shops it's not so cheap anymore.
On the other hand, if you have absolutely no other use for acid you already
have anyway, and you can get the KOH or K2CO3 cheaply, and you have the
time to wait for it to dry or are willing to spend the energy for forced
drying, why not?

If your looking for KNO3, you may buy it at any feed store or harware store
as "Stump Remover". Just dont buy the "Stump Out" Brand. For more info on
this go to Richard Nakka's site, he has a wonderful site.

Ouch, i forgot it! You can buy KNO3 on e-bay site: thei shell 500g of KNO3
powder but I don't remember the price.Bye

Mad chimica?
e che è?
io sono iscritto a it.scienza.chimica
ma mi faceva piacere anche tentare un po' con l'inglese.Così magari lo
imparo meglio!
sempre che non dispiaccia eh?
tu come mai parli italiano?

beh!vista la mail mi pare ovvio!!!

DRAGON(r) stump remover has potassium nitrate but I don't know what
proportion. Dragon Nitrate of Soda acts as an oxidizer when making
blackpowder.
