Aqueous solutions of ammonium nitrate and potassium chloride are reacted to exchange the ions and form potassium nitrate and ammonium chloride. Filter the solution and either set it in the freezer to chill or else put it in an ice bath so you can observe the crystallization of the potassium nitrate. Make Potassium Nitrate Collecting bat guano from caves used to be the main way to obtain potassium nitrate - also known as saltpeter - but these days there's a much easier way to get what you need to make this basic component of science experiments, fertilizers and gunpowder. The ammonium chloride is much more soluble in water than the potassium nitrate, so you will get potassium nitrate crystals, which can be separated from the ammonium chloride solution. It occurs as a mineral niter and is a natural solid source of nitrogen. Depending on the objectives and available resources, the nitrate may come from sodium nitrate, nitric acid or ammonium nitrate. Heat the solution with 37 g potassium chloride to dissolve the lite salt. Pour off the ammonium chloride solution, leaving the potassium nitrate crystals.
