How to Make Potassium Nitrate

I create KNO3 using household chemicals following NurdRage's tutorial. I made the KNO3 using KCl and NH4NO3.
KCl is found as No Salt a sodium free salt at some stores.
NH4NO3 is found in instant cold packs.

Equation to make KNO3: NH4NO3 (AQ) + KCl = NH4Cl (AQ) + KNO3 (AQ)

The solution is cooled and the KNO3 is precipitated out.

anyone else not wanting amonium gas in there face

@opaldragonmb I don't believe any ammonia (NH3) gas is produced in this reaction:

NH4NO3 + KCl = KNO3 + NH4Cl

where did u get instant cold pack plz REPLY

@clayton3610

I think I got it at CVS or Walgreens.

BALL MILL THE POTASIUM NITRATE!

[roman9900354345345]

lol you can make KCL yourself if you burn flash powder

[TheCombatarmshero]

You know there is another way of making it, this way is an ancient way but still works, put stale urine in a jar with straw, wait a coupl months then filter the straw through water, take that water and filter it through wood ash, then dry the solution, I'm not gonna explain all the science though

[nicholasdoran]

let it sit out in the sun, perhaps? that might work...

[coolstulf]

you need to make a deskator bag with amona nitrate sub scribe and ill sho you how to make one bro

[ambrose899]

Simple displacement reaction~?

[zaymaniac]

bro two words (desecator bag)

[MsCandyko]

boil it

[MultiNerfaddict]

can ordinary salt can be used

[Ryuuken24]

The reason it was still mushy, is because, you need to have it dry out with normal room temperature, that means, don't put a cap on it, the water in the mixture will vaporize at room temperature. Guess it's too late now, ain't it, 2012 :D

what is an anti-kicking agent and how to i find out if my ammonium nitrate has it?
