What is this? Never heard of such a thing. I red on quora that KNO4 is an impossible compound.

You are right, this compound does not exist, or at least not in a solid stable form. It looks to either be a scam, or a sneaky way to sell perchlorates in the EU.

I expect that if you place an order, it will be delayed, and you'll get store credit rather than a refund. If it does exist, it would be O2NOO, rather than have four oxygens bonded directly tot eh N.

What about this one: https://blast-tec.com/vare/potassium-perchlorate-solution-kc...

40% KClO4 in water, that's impressive.

Maybe it is something like sodium percarbonate. From Mellor's Comprehensive Treatise vol. 2 (Library or Internet Archive):
Quote:
According to S. Tanatar, when an alkaline solution of sodium nitrate is treated with hydrogen peroxide, and after evaporation at 50° until crystallization begins, treated with alcohol, crystals of a salt, sodium peroxynitrate, NaNO3.H2O2. 8H2O, are formed.


If we make some rather questionable regrouping, it becomes NaNO4. 9H2O, an eneahydrated sodium pernitrate. For practical purposes there's an extra oxygen there.

I wouldn't buy it.

They do say “<40%” so it could very well be a 1.5% saturated solution, or possibly even less! ;)

I have bought that one before. There wasn't much water in the bottle...

The KClO3 was very wet though.

From reading elsewhere, it appears to simply be dampened potassium perchlorate powder.

Ah, I see. It's a "solution" to bypass some regulations. Nice :-)

Apparantly it is gimmick to get around the restrictions on perchlorate to individuals in EU. It is a blend of 60 KNO3 and 40 KClO4.

I simply love this way to show middle finger to EU - exactly according to their rules :D.

I second this! :D
Love it when they beat them by playing by the regulations they made.

The regulations are designed to slow people down not stop them from acquiring chemicals. Really, regulations are designed for the lazy, timid, and wreckless. These are the types to get in trouble, hurt themselves or others.
