iS 99% KNO3 fine for most reactions?
so today i got a pound of Gordons Stump Remover cuz it was only $8 and i knew it was 99% KNO3 and 1% Calcium Stearate. IS there a way to remove that
or is that fine for most reactions?

I have used 99% KNO3 with (SiO2) anticaking and without.
I havent noticed the slightest difference.
I guess it depends on your use.

Recrystallization. Calcium stearate is barely soluble in water.
This just in: 95,5 % of the world population lives outside the USA
You should really listen to ABBAPlease drop by our IRC channel: #sciencemadness @ irc.efnet.org

It should be fine, I've used that in the past and works well enough, as long as it's over 90% you should be fine.

I have used stump remover KNO3 that had some kind of oily coating, possibly it was Ca stearate. This was the least satisfactory KNO3 that I have
used. The pottery grade is much better. I would try to remove that stearate: perhaps by washing with an organic solvent. Or use recrystalization.
The single most important condition for a successful synthesis is good mixing - Nicodem

That should work as longs as its is property ground up. It need to be in a somewhat fine powder or better. (To get best results)

Sorry to borrow on your thread but seems a good injection point, I see no reason why HCL could not be used for making of nitric acid to end with the
chloride salt. Or am I missing some thing obvious, I all ready factored int he water as the goal is Azeotropic HNO3

Also, hydrochloric acid is volatile, or at least it is more volatile than sulfuric acid.

99% Purity should be fine for most reactions, although if your experiment is very sensitive you can purify the KNO3 via recystilazation, Calcium
stearate is extremely insoluable in cold water.
