Justinkkk Posted January 10, 2015 Posted January 10, 2015 I want to make my own kno3 from gunpowder. I obtained gunpowder from a nearby shop. Can you tell how to extract kno3 from it?
Sensei Posted January 10, 2015 Posted January 10, 2015 (edited) Do you realize that KNO3 you can get in normal market shop with food.. ? At least here.. It's used to pickling meat.. I bought it not once. In Leroy Merlin also they sell it. One way that comes to mind, although I have not tested it, is using water. KNO3 is soluble in water, while carbon and sulfur, not. I would try filter column (like below) and leave it alone for days or weeks and see what happens. Edited January 10, 2015 by Sensei
Torben Posted January 10, 2015 Posted January 10, 2015 KNO3 is used as a fertiliser. You can buy it at a garden centre or in petshops as an aquarium fertiliser.When I was a kid I used it to make smokebombs
