    Glad you asked! The stump remover is already >98% KNO3 to start with. I did not record how much was lost in the process because I used the purified crystals as a lab reagent and saved the remaining dirty stuff for pyrotechnics or things that don't require KNO3 of high purity. Potassium nitrate will not evaporate from a solution, just the water, so virtually none is lost at all using this process. Repeating the process will continue to purify it but really isn't necessary in this case.

    Fantastic video! It was really cool to see the crystals forming as you decanted off the water. Potassium nitrate crystals are really pretty. It would be cool to look at them under a microscope. Remember. If you aren't part of the solution you're part of the precipitate!

    Great video! When I perform procedures like this, I typically vacuum filter the hot solution. This removes suspended particles and other solid impurities. I've seen a brownish murky solution of nitrate fertilizer go to nearly clear after just to passes. And of course you can always perform multiple crystallizations if you need a really pure product.

  • @TheChemistryShack

    I would recommend another recrystallization. Since you didn't rinse the crystals with ice water after decanting the solution, the wet crystals have the impurity-filled solution stuck to them. Thus the dry crystals will have impurities in them

    What you make here is called Supersaturation solution which means dissolving the maximum amount of substance in the water…if you want to get pure Chrystal you need to add more distilled water, than after cooling , the kalium nitrate crystals clearly droppings to the bottom of the solution, you can pour out and collect those crystals but in your case because the solutions is Supersaturation, once you stopped heating , crystals are forming everywhere quickly, makes no chance to separation the Impurities ..

    Great video! Do you happen to know approximately how much of the stump remover is lost during re-crystallization? I know that the total mass after the saturation etc. will be lower because the impurities are removed but is any actual potassium nitrate lost (due to evaporation etc...)? If so, would it be smart to cover the liquid until it has crystallized? Also I know that some purification methods should be repeated, is this the case for stump remover? ~80+% purity works for me. Thanks!

    Shouldn't the crystals be rinsed with cold water to remove the contaminates in the liquor that is sticking to the crystals? If you succeed in removing 90% of the liquor, by decanting only, you have removed only 90% of the soluble contaminates at best (assuming the re-crystallization perfectly excludes the contaminates).

    Well you have the refrigerator pump, it makes really good vacuum on the other end use it for real vacuum filtration, I do that all the time. After some time it is necessary to add some motor oil to the pump via vacuum side and eventually it will seas from rust. WD-40 helped My one but after year of service I think I need a new one. At the beginning I was worried about the temperature of the pomp but now I run it constantly so it is too hot to touch it. It still works.

    Stump remover is not 100% in the pyrotechnic (firework) usage. As far as usage of stump removal, Spectracide claims 100%, but it still has some impurities. Also, there is a problem with the decanting . When allowing the crystals to dry if should be in a very dry area ( little to no moisture in the air)

    The result would be that you wouldn't be able to get as much out of the recrystalizations. That's it. You would just end up with a saturated solution that may not precipitate as much of the product. Essentially, you would just need to boil off some of the water and continue with the recrystalization.

    The room temperature collection was only because he was in a hurry, and is not necessarily needed But, the purity of the crystals will be somewhat better than the crystals at the end of the recrystalization. One could take the saturated solution at the tail, heat it up, and boil off much of the water until the remaining solution is saturated again at 100c with crystals beginning to form, and then pull it off the heat and let it recrystalize. Finishing the first Recrystalizing of the tail end solution, if added to the first recystalization, will result in a better yield collecting much of your starting material, but the recrystalize tail end won't be as pure as the the first batch because the contaminated solution is more concentrated with contaminates. But recrystalizing the tails of the tails will provide increasingly diminishing returns with increasingly dirty product. Obviously the small amount of finished recystalized tail ends can be recystalized a second time to increase their purity before adding back to the first batch. What is left is probably best to be evaporated forming dirty impure crystals which can be used to fertilize soil with Nitrogen and Potassium or used to make pyrotechnics.

    You can probably get away with a single 1000mL beaker. Personally what I use is 1000, 800, and 500 and 250. Sometimes its nice having more than one nearly the same size you you can decant supernatant from the 1000 into the 800 or you can filter a solution into a beaker. If you don't have 2 beakers you can't filter a solution.

    No. 7 years too late but no. Just go online type Potassium Nitrite in google it'll pop up a 10 pound bag of 98% Potassium nitrite and it comes in small pellets, you can either use his method or use a mortar and pestle or coffee grinder and turn it into a fine powder if you are just using it for BP no need to do his method thought I am going to try this and see if it has an different effect then the powder. My guess is it either won't or if it does its only because I will be able to get the crystals into a finer powder with the crystals. I am going to try a flash powder with both as well just to see if that has a different effect on how well it burns. I extracted about 30 grams of flash powder from fireworks this year and I added in a spoon full of my potassium nitrite and a spoon full of Indian Dark Aluminum powder today hopeing that I wouldn't ruin it and I decided to make a triangle cracker by taking a mortar fuze from breaking the fireworks down and putting it through a small hole in the corner of an envelope and then I took about 12 grams of my mixture and folded it all up and then I decided to tape it up with electrical tape nice and tight to stop any powder leaking out and before I did it I thought "hmm maybe I should test a small amount 1st so I took maybe 400mg of the powder and lit it and it flashed so damn hard I decided maybe it wasn't the best idea to do the triangle cracker I made near my house when it isn't legal to do fireworks or there isn't rain or snow on the ground because people could care less if it were those situations but mid summer during a drought year when we've had fires all over the state already. So instead I took a sticky note, rolled it up backwards so it stuck to itself in a cylinder and I used electrical tape to hold it in place well it was still on the pen and pulled it off 1/4th the way and bent the end up and taped it and then I filled it with the flash powder and took a firecracker I broke in half and put it on top of the powder in the tube and taped it in the tube so it looked like an extra long firecracker with electrical tape all around it and lit thay instead and I gotta say I am damn lucky I didn't just light the triangle cracker that had about 20 times the amount of powder in it because that little fire cracker made a thud that I was worried might get me introuble 😆 it was about 10 times more powder then a normal little firecracker so if you think that probably had 500-700mg of powder and the triangle cracker was way fatter then ones youd normally see my guess is when I actually do it its going to make a boom that shakes windows 😆 I am actually going to take it to a feild nearby to avoid any issues because I was absolutely shocked by how adding a scoop of those two powders made the powder extracted from fireworks so much stronger then it already was. I am glad for now I live in am area where it would be looked down on to make giant salutes because I'd love to use KCIO-4 in F.P. instead of KNO-3 however once I get my ATF licence in Nov. It won't matter anymore and I am then moving 9 hours away to where I am away from highly populated areas and it will no longer matter if I decide to go outside and light of salutes off. I will also have a bunch of different jobs I can get out there because my entire family lives out there.

    I freaking LOVE how everyone thinks Potassium Nitrite is a big secret and it's either super hard to get ahold of or magically going to disappear if someone finds out what company sells it 😆 you can get a 10 pound bag for $21 plus shipping and have it to you within a few days 😆 I can't get over the comments I've seen and things people have said in they're videos about Potassium Nitrite. Brothers and pyro sisters ... Potassium nitrite isn't going anywhere and its literary as cheap and in some cases cheaper then a bag of good potting soil. You can get everything you'd need to make several types of flash powder and black powder at home for under $80, and that's with buying sulpher and potassium nitrite in 10 pound bags. Trust me I just did it, and I use to make m-100's 8 years ago. I am not going to be mixing up flash powder until I get my ATF licence this November because I'd rather not risk my chances at following my dreams of working in the pyrotechnics field however I did mix up 25 grams of B.P. tonight and light it all off at once since it was my B-day and I wanted to end the day with a whoosh. Lol it wasn't really a woosh because B.P. has such a slow burn rate and I didn't get my willow charcoal into a fine enough powder. Next time I won't make that mistake and I am going to add some Zinc to the mix and see if it turns the flame green because that would be epic to see a Black powder with a green flame

    Loutcho Bix The idea is that crystals tend to be very pure, so when you recrystallize, you mostly get the substance you're purifying in the crystals, while most of the impurity remains in the liquid. When you pour off the liquid, you're pouring off concentrated impurities. Of course, some of the stuff you're purifying is still dissolved in the liquid, so that gets tossed out too. Basically, the process concentrates what you want in the crystals, and concentrates what you don't in the liquid. Of course, this isn't perfect, you still get impurities in the crystal and the stuff you want in the liquid.

    It's a re-crystallization, so all solids should be 100% pure KN03. However, he didn't rinse it before decanting, so impurities were never washed away, thus the KN03 is impure. If you wash it, it should be pure. I don't know what to wash it with through, its is slightly soluble in ethanol so that seems like a bad idea

    Great idea. I wonder if this stump remover idea is cheaper than buying potassium nitrate from a firework source, but then I don't know how much purity is required for good black powder. You would definitely have to ball mill it into a fine powder to make it firework grade.

    A lot of brands have dirt mixed in with it, which can be detrimental to some reactions. Every time I dissolve and filter mine there is always a lot of insolubles in it. About the only way to buy extremely pure KNO3 is to get it from a chemical supply company that specifically supplies it for chemistry. I know I don't want dirt in my KNO3 when I make nitric acid.

    Its cheaper to buy it. It's sometimes used as a food preservative or more common as a fertilizer. But you could mix potassium carbonate with nitric acid, but that's not safe.

If you were doing that, you would not really need to because you wouldn't be using stump remover, you would use reagent grade stuff, Thats all I am really saying,.
