Make Potassium Nitrate from Instant Cold Packs and Potassium Hydroxide Warning: This reaction will produce large quantities of toxic ammonia gas. Perform the reaction outside or in a fume hood. Potassium hydroxide is highly corrosive; wear gloves when working with it. Also note that this video is for those interested in the chemistry, it's not cheaper/better/easier than buying it. Take 60g of potassium hydroxide and combine it with 80g of ammonium nitrate. We showed how to obtain ammonium nitrate from instant cold packs in a previous video. Potassium hydroxide is sold online to make homemade soaps and for biodiesel. Now add 30ml of water and gently heat the mixture. It will first bubble as it releases ammonia gas and then continue heating until it boils. Let it cool and evaporate to dryness. If you don't want to boil anything, you can pre-dissolve everything first before mix them. Use 100mL of water for the ammonium nitrate and 50mL of water for the potassium hydroxide. When both solutions are clear and ready, add the ammonium nitrate solution to the potassium hydroxide solution. This step will produce large amounts of ammonia gas and must be done outside or in a fumehood. Leave the solution in a very well-ventilated area (outside is best) for all the water and ammonia to evaporate. You can also boil the solution to dryness, just remember it is still producing ammonia. Now you have potassium nitrate! To test it, mix a small portion with an equal amount of sugar and set it on fire. Normally pure sugar does not burn but if the potassium nitrate works then it will flare up in a purplish pink flame.
