KCL from KNO3
Can KCL be made from KNO3 ? (Use KNO3 for K source to make KCL)

Yaes, it can.
Why on earth you would want to is a mystery.

KCL doesn't exist.
KCl does.

KNO3 + HCl = HNO3 + KCl ?
maybe

That's not a chemical reaction. You obtain a solution containing H3O+ ions, K+ ions, nitrate ions and chloride ions. On chilling KCl might crystallise
out but you'd have to check the solubility limits first.

This will work, since HNO3 will react on heating with excess HCL to form NOCl gas which escapes, at the end you will have KCl and HCl only. A
pointless thing to do, btw..

I doubt that would work as well as you imagine.
The equilibrium for HCl + HNO3 === > NOCl lies much to the left. And HCl is volatile too.

At least I've heard that gold recovery people use excess HCl to "neutralize" remaining HNO3 from aqua regia, I think more or less it works.

They must be some d*mb f*cks. You need Aqua Regia for gold anyway. Excess HNO3 is usually neutralised with urea, among the 'gold diggers'.

They have vastly different boiling points though. Ensure that there is enough water present to form azeotropic HCl, and reflux the mixture using cold
water in the condenser. NOCl won't condense, but the acids will. That should drive the equilibrium to favor the destruction of HNO3

But you don't think that would be a pretty dumb way of doing it? Nice, massive fumes of NOCl, yum yum!

A dumb fuck called nurdrage calls for something similar while purifying crude chloroplatinic acid in this video: www.youtube.com/watch?v=MlMj3VEYBMA
But I'm not going to argue more..

False analogy alert. The gold diggers aren't looking to produce chloroauric acid.
And converting KNO3 to KCl the way you propose is a dumb waste of nitrate, especially seeing how easy KCl is to obtain or even prepare. I hate these
idiotic DIY schemes.

I never proposed this method myself, I even called it pointless, I however said, that this is theoretically possible (contrary to what you initially
said).

It is posible but is waste of chemicals.
In my country dietetic table salt ( 66% ClK,33% ClNa) is posible obtain ClK with repeated cristalisations.

Yes, me too! Interestingly the author never appeared again to tell us why he needs to convert more useful (at least I think so) nitrate salt to the
cheap chloride.

My bet: the OP will NEVAH do that. That's how most of these 'How can I make sodium carbonate from BBQ coals an' sh*t, also, too' threads nearly always
end up. I should avoid them like the plague. I only wanted to correct a spelling error (boohoohoo... hoohoo)
